Quick and dirty fix for the ffprobe error

Changes

• A bug with ffprobe happens only when there is no opened console. As a quick fix, there is now a console which opens when using the program.
• ffmpeg and ffprobe are now embedded within the binary.
• The download progress bar is slightly different.
• Logic of the query has been revised. Priority it to compatibility (x264 codec) then searched resolution independant of the codec, then compatibility and then whatever it can find.

Fixes

• A lot of unhandled exceptions when infos aren't found.
• Use of a more robust method to get the total duration of a media.
• The logic when querying a specific resolution has been fixed.
