Wire boundary hooks into player movement

Browse source 
Movement now evaluates boundary enter/exit conditions. Exit checks can
block movement based on carrying items (by name or tag). Enter and exit
messages sent when crossing boundary borders. All boundary logic lives
in move_player() before position update.
