Folder view from solid explorer

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 on disk looks like. This example is a single cuesheet with 5 separate hour long mp3 files (its a electronic/trance mix i believe).This is how it will now appear in GMMP 3.0Cuesheets can also be embedded into the tags of files. GMMP supports that as wellNext up will be the new equalizer / effects UI. I will most likely also rewrite a lot of the underlying DSP/EQ code as well.
