Fixed quality being required when downloading, causing any videos with the best quality being lower than the one selected be undownloadable without selecting "best" (Download.cs)
Fixed audio not downloading (Download.cs)
Fixed the unnecessary amount of new calls in settings, for some reason... (frmSettings)
Moved 8K to the top, it fits better there. (frmMain, Download.cs)
Not available in this version, but being worked on:
Added batch downloading (frmBatch)
Added file merging (frmMain, Covert.cs)

Consider the compatible branch a different application due to the amount of code changes.
