Huge convenience update!

Update 1.4.0 brings multiple new features, as well as some fixes!

Additions:

• The GPL-3.0 License
• Filtering clip titles via regular expressions
• Filtering clips in multiple categories at once
• Filtering clips from multiple clippers at once
• Downloading clips from multiple streamers at once

Fixes:

• When a clip download is interrupted, the partially downloaded clip is now deleted from your drive
  This makes sure it is not skipped when running the tool again
• Various spelling mistakes, etc.

Minor stuff:

• Replaced my donation link with a cooler, non-custodial tip jar
