FIX: website/vimeo: Reimpl. support

  - Improve stream identification (incl. height, bitrate)
  - Use HTTPS if then input URL was given using it [1]
  - Use "best" quality stream for "default" stream
  - Parse data from a new location
  - Update all relevant patterns
  - Remove code bloat

This fixes the reported issue [2] affecting the 0.4 series.

Notes:
[1]: media streams are still provided over HTTP
