Remove name, description from GameObject table in favor of k/v data; use shortname where appropriate

This might open a pandora's box of state but i'm hoping that a lot of the places we use name we can use shortname.

it's probably wise to add properties for name and description but not setters -- i want them set only through WITCH.

If name gets corrupted or deleted, the shortname can be used.
