General menu creation for addon - both for setting FFMPEG PATH when installing and preferences for when it runs.
Addon now reads video files from folder

Addon now reads video files from folder and throws them to a FFMPEG command that must be reviewed.
FFMPEG for proxies almost OK

Must change options: user should be able to choose between prores and mjpeg codecs for both proxies and fullres files.

The addon is now functional. Is only misses a way of toggling between proxies <-> fullres files on VSE's timeline.
Changed "warning"
Added shortcut and editing toggle

Added Ctrl+Alt+Shift+P as shortcut and class to toggle between proxies<->fullRes videos at VSE timeline. Addon ready for use.
