Split off portions of externs.h and enum.h into other files. The

crawl_environment, player and monsters classes have been left in
externs.h, which necessitates that all of the enums references by
those classes stay in enums.h, since you can't forward declare an
enum.  However, it's a start.

Also, portions of misc.{cc,h} have been split off into traps.{cc,h},
place.{cc,h} and terrain.{cc,h}
