Added plugin FileMonitor and updated RenameFile plugin

[David-Maisonave]

Plugin FileMonitor.

I found the stash-watcher script after I started implementing FileMonitor, but stash-watcher has some issues.

stash-watcher Issues

• It doesn't work as-is. I had to make some changes in the code to get it working.
• After fixing it, I notice that when a change occurs in the file system, stash-watcher performs a full scan on everything in the library, instead of just scanning the path (directory) with the change.
• stash-watcher does NOT fetch the stash library content, and instead user has to populate a *.toml file with desired paths. If the library content changes, the user also has to change the *.toml file.
• Can not start the script from the Stash GUI. Not user friendly since user has to be familiar with launching python scripts.

FileMonitor

FileMonitor is similar to the stash-watcher script, put it works like a Plugin.

• The user can start it from the Stash UI in [Plugins Task]. And the user can kill it from the [Task Queue]
• FileMonitor automatically gets all the Stash library paths, and monitors those paths.
• When a change occurs, it calls stash.run_plugin_task with the directory of the changed file, so only the effected path is scanned.
• FileMonitor runs out of the box without the user having to make any setting/configuration changes.
• FileMonitor can also optionally run as a standalone script.
  • To start monitoring, call the script and pass any argument.
    • python filemonitor.py start
  • To stop FileMonitor, pass argument stop.
    • python filemonitor.py stop
    • After running above command line, FileMonitor will stop after the next file change occurs.
    • The stop command works to stop the standalone job and the Stash plugin task job.

Update to RenameFile plugin.

• Added fields galleries, resolution, and width.
• Fixed bug associated with studio.
• Added logic to limit the log file size.
• Added logic to only get [Change success] logging when no errors occurs.
• Change default fields to include studio.
• Added postfix styles, which was mainly needed to properly format resolution field, but can be used for the other fields.
• Consolidated [Include Existing Key Field] options into one option.
• Cleaned up code and updated version

Please remove manifest files. They will be generated by the build action. Also .gitignore seems to be related to debug/development, not relevant for regular users.
