Commit a large update to lumina-fm:

The entire backend has been rewritten around multi-threading, and is much faster and more responsive now.
The entire browsing widget has been redesigned for a better workflow and cleaner UI.
The tabs/columns "group modes" have been removed. Instead, tabs are always used, but each browser supports a single/dual columns *within* each tab (via a couple simple buttons on the toolbar). Each column within a tab will share the same interface buttons (toolbar actions, ZFS snapshot slider,etc) - and they will reflect the settings on the "Active" column (with appropriate visual changes to indicate which one is active).
The icon size options have also been removed from the menu bar and are now a couple small "zoom" buttons on the browsing widgets instead.

KNOWN REGRESSION:
Keyboard shortcuts have not been tested and re-added as necessary yet.
