MediaPlayer: Relicense to MIT

* The GPL license here was a relic from the past to help
control YellowTab's use of Haiku source code. The intent
at the time was to relicense MIT. Some GPL parts remained.
* This is going to get harder and harder to correct over time.
* This code makes Haiku *not* MIT. Lets correct that.
* I reached out to everyone who made changes to these files and
got personal approvals to relicense MIT.
* If I missed somebody, *and* you feel as though the MIT license
doesn't meet your needs, please contact Haiku, Inc. and we will
work to revert your changes.

MediaPlayer: reworked info window to use layout API.

* Use BStringViews instead of BTextView - it's more flexible (truncation,
and tool tips), and allows for fine grained updates.
* The file name and location views are now showing tool tips with their
full contents.
* Also, its look is now less exotic, if boring.

* Coding style cleanups, no functional change.
