Display author, title, license in the level editor music browser (#2617)

Whenever any of author, title and license fields are defined for music
files, help text showing this music metadata is displayed when hovering
over ".music" files in the level editor music object file browser.

This commit adds both the software implementation and author, title,
and license values added to SuperTux music files in data/music.
The game credits and data/AUTHORS are updated in some cases where there
is new authorship data.

Fixes #2617.
