panel: map

[yankscally]

a panel for interacting with the special bless map collection as described in #10 , which handles convex/trimesh collisions for all the contained objects, but can also be used to oversee properties related to the root "node" of the map. if no object in a map is selected - or - if there is no map in the scene, the panel will have operators for adding maps and levels.

• distinguish the difference between maps and levels (sub-maps)
• in the map workflow, there could be sub categories like structure, structure_piece, room. etc

map collection properties:

• is_map internal property for marking and recognising the special collection - to show the panel only when selected. else we can show an "add map" where we can add a map collection.

• is_trimesh if you want all objects in the collection to have trimesh collisions, if false apply convex (default)

if collection is a sub-map (collection inside map):

• ignore_collsion skip this collection and dont add any collisions
