Added main function and related functions. Added functions that take a char-struct and room-struct to item and npc modules (as prep for calling perform-item-transaction and npc-encounter).
Un-refactored character and combat (they didn't need to be split).
Fixed some bugs related to the use of (member ...) and '(*lists* *like* *this*) (they result in lists of symbols rather than lists of constants).
Moved map-e::in-dir to utilities and renamed it.
Added update-room-at-coords helper in room-common.
Fixed other assorted bugs.
Removed Resources/Rooms/1-1.txt from source control (it's a generated file).
(Apparently, clean/incremental diffs are considered overrated tonight.)
