[feature request] support for .lrc files/lrc display and/or editor

[STimOv]

lrc is a standard for synced and unsynced songtexts. It allows usage of time marks like:
[00:01:57.20]This is a line of your songtext and will be displayed at 1 minute, 57 seconds and 20 hundreds of a second.
[00:02:00.00]at 2 minutes this line will be displayed and the previos one disappears

additionally it might be possible to mark the text slowly in a different color, from the beginning to the end of the time a line is shown.. a little like this:

an own editor could also be an option. Also storing found songtexts form the www to local file or creating new ones and myabe editing it (fixing errors or adding timer codes for syncing, creating a completely new file)

lrc format is a very simple one, with only limited features. So it might be an nice litte project implementing it (of course there would be some work to be done)
