- verify_freespace will now log that a file is locked for access and
return True on the free space (would stop PP if a file could not be
read)
- isFileLocked will now return True if a file cannot be checked by
os.path.isfile()

Effectively logs a locked file correctly now when a file is locked for
either reading and/or writing.

- When copying or hardlinking checks if the source file is locked for
reading
- When moving or moveAndSymlinking checks if the source file is locked
for reading and writing

https://github.com/SiCKRAGETV/sickrage-issues/issues/1338

- Fixes issues where a snatch history returning quality 'Unknown' is
accepted as an acceptable quality without trying to get an actual
quality from _get_quality()

Changes the Associated files check when running during PP (subfolders =
False) to do the following:
- Lists all files in current folder
- Loops through each file and checks if they are the same as the
videofile in a case-insensitive way

This is needed because both glob.glob and fnmatch act in a
case-sensitive matter on case-sensitive file systems.

Should fix https://github.com/SiCKRAGETV/sickrage-issues/issues/1117 for
the most part. Differently named files (not only case differences) will
still be missed

* Improved speed of Watchlist and Collection Check
* Collection Add is by episode not by show
* Option to remove items from collection if they do not exist in your
Sickrage Library
* Moved Trakt code out of post processor and into Notifier
* Fixed Notifier to correctly add all episodes of a Multi-Episode file

episode.

Prevent conflict between regular and special episode(Same airdate)

- Changed the call to verify_freespace to check against show_location
- Changed the oldfile check to only check if oldfile.location actually
is a file.

- Adds check for quality even if SR initiated the download

is_priority will now return False if the episode status is not snatched
and the new quality is lower than the old quality (or lower or equal if
its a proper)

https://github.com/SiCKRAGETV/sickrage-issues/issues/1023 for more info

- Checks free diskspace on destination before deleting old episodes and
copying/moving the new one over.

- List_associated_files would check the wrong folder when deleting files
- Fixes issue when downloaded file has the same namepattern as the old
file. Would then proceed to delete the new file.

Hotfix, merge with master and develop

- Changed NameParser to include trySceneExceptions boolean
- Changed calls to NameParser from Post Processing function to include
trySceneException=True when tryIndexers is also True.
- Changed get_show function to try looking up a parsed showname in the
scene exceptions table (using get_scene_exception_by_name) if both cache
and Indexer lookups fail and trySceneException is True.

- Changed PostProcessor._delete to include base_name_only = True, and
subfolders = True

Makes sure that when replacing old episodes in PostProcessing ALL the
old metadata is deleted, including those that have an addition to the
filename (-thumb.jpg) or are in subfolders (.meta and .metadata
subfolders for some mediaplayers).

Fixes https://github.com/SiCKRAGETV/sickrage-issues/issues/842

- Changed setting base_name to use the old way when subfolders is not
true.

- Changed list_associated_files to allow for skipping subfolders
(hopefully fixes files being deleted before being processed)
- Changed delete_files to allow forcing of deletion (fixes RAR contents
being left unpacked when processresult not True)

This does leave one issue that is the cause for RAR contents being left:
namely that result.result does not get properly set on VideoInRar files.

- Renamer now correctly handles metadata files that have add-ons to the
filename itself (fixes
https://github.com/SiCKRAGETV/sickrage-issues/issues/358)
- Renamer now correctly handles subfolders for metadata (fixes
MediaBrowser and TiVO metadata renaming issues)

Re-coded logger facility for better performance and cleaner code plus has better code for rotation of logs.

Prevents the error log in webinterface from filling up, if there are downloads in your watch folder, which aren't in SB list

Added ability to set a default indexer for trakt notifier used for adding shows from watch list so that SickRage knows what indexer to set the show as.

Indexer mapping now uses indexer api calls to gather its information and then stores it to a new table called indexer_mapping for instant lookups later on.

Fixed trakt related issues for adding new shows and syncing.

Centered items at bottom of pages to just look a little nicer and fit properly.

Newznab providers now create season search strings for all searches as single ep search strings combined with using rage id numbers seems broken currently.

Fixes issues with scene exception updating when editing a show, should resolve problems with it duplicating scene exception name over and over again.

Reduced DB sleep timer to increase overall performance of application.

Improved generic queue code for threading.
