Program groups and items

[freedom7341]

Write a new format for the program group and program items and create working program groups with corresponding MDI windows. Preferably implement dialog functionality for creating these program groups before Alpha 1.

Memory management implemented, groups and items can now be created (groups can be removed but item removal is still WIP). Listview implementation needs to occur now which, for me, is the hard part. Expect delays.

listview works now, working on getting/setting item info, item removal still going to be put off, items don't have pictures yet

[freedom7341]

programs and items have a basic implementation now, i'll do a new issue when i'm about to extend their functionality, programs launch now.

reopening, will close again after i fix the following:
cannot delete program groups or items
program items don't save properly between restarts
cannot edit program groups or items
