Get the lumina file manager ability to detect mounted external devices working completely, using the new LuminaOS class in libLumina.
Update Lumina to 0.4.1:
1) Added the Lumina File Manager to the build
2) Setup lumina-open to use the file manager by default (unless alternate default given)
3) The file manager is not completely done yet: will move to version 5.0 once it is finished.

The current features are:
1) Ability to browse the local filesystem
2) Set/manage bookmarks of favorite directories
3) Detect currently mounted external devices and quickly go to them
4) Auto-completion when manually typing/browsing a directory
5) Fully setup keyboard shortcuts
6) Detect/restore files and directories from ZFS snapshots
7) View a slideshow of all the pictures within the current directory
8) Multi-tab setup: with each tab having it's own distinct browsing history.
