GoneMAD Music Player

Most of the work I've done since the last post has been behind the scenes so there is not too much to show.  I rewrote the audioengine management piece (what handles the interaction with gonemads audioengine, android media player, and chromecast), rewrote the crossfade code, and cuesheet handling. Cuesheets are something that the majority of gmmp's user base probably does not use https://en.wikipedia.org/wiki/Cue_sheet_(computing), but they are a nice feature.  For those who do not know, a cue sheet allows you to listen to a single large audio file as if it was split up into tracks for each song.  GMMP has always had decent support for CUE files (they would appear as individual tracks in the library views), however in the folder browser they would just appear as a .cue file and the single mp3 / audio file.  In 3.0, the folder browser will actually extract and list the individual tracks in a CUE instead of the single file. Below is what the actual folder ...

Next up on the new UI list is the file/folder browser.  I also rewrote the file/playlist handling on the backend to be much more streamlined.  A lot used to go on when playing folders and i've greatly simplified that.  As always, the file browser will show anything on the file system and does not care if its in the database or not.  This is great for navigating, but caused a lot of issues when a user went to play a file or folder.  I am sure some were familiar with the issue where songs would "disappear" from the queue after reloading GMMP.  This was because the user played a file that was not scanned into the database.  GMMP would play the file fine in the queue, but when the queue was persisted to the database those files were lost.  In 2.x GMMP would try its best to get everything scanned in by running silent scans of folders as you navigate into them.  While being pretty inefficient, it worked for the most part.  The big issue happen...
