Implemented .des file caching (speeds startup a fair bit): .des files are

parsed only once (unless they're modified again). Crawl also keeps only map
stubs in memory (name, place, orient, tags) and loads the map body only when it
is actually selected by the dungeon builder.

This probably breaks the Windows build, will be fixed soonish.
