Commit a major overhaul of lumina-fm: PLEASE TEST!!

1) Seemlessly embed the ZFS rollback options into the main dir browser (simple time slider at the top).
2) Take all the main widgets and put them into separate classes/files (widgets/*)
3) Add support for both tabs and columns for multiple directory viewing
4) Remove the "icon" view mode, and replace it with an icon sizing option (larger/smaller)
5) Add the ability for the multimedia player and slideshow viewer to be running within separate tabs while still browsing the system (new files will be added to the queue instead of replacing it)
6) Ensure that only selected files are added to the player/slideshow on demand.
7) Add the ability to zoom in/out on a slideshow image.

KNOWN ISSUES:
1) The new file/dir functionality has not been replaced/re-implemented yet.
2) The drag and drop functionality has been removed until a new implementation is put in.

PLEASE TEST:
ZFS snapshot use, multimedia file player, browsing and other UI changes
