Small behavioral adjustment

• youtube-dl or youtube-dlc now choosable
• --playing flag makes aytdl downloads only one video (not the full playlist)

Note: the old pyinstaller build system is not functionning anymore

various fixes : 1.2.5

Fixes various things, moves to youtube-dlc instead of youtube-dl since the latter appears to be a bit outdated (and doesn't work!) in the repos

Binary (linux) for v1.2.3

Merge branch 'master' into dev

First windows-compatible release

Get the binaries for your system (aytdl.exe for windows, just 'aytdl' for linux), but don't forget to read the instructions!

Binary distributed

full auto-ytdl v1.1.2 with a binary executable (but dependencies need to be installed manually)
