Subject: Another batch of msvc compile fixes. Added wrapper implementation for
 opendir/readdir Other functions left stubbed out. It's a shame that crawl's
 "direct.h" conflicts with <direct.h>. Fixed up use of AppHdr.h in a couple
 places (it must be included first); changed project to use precompiled
 headers.

crawl now compiles cleanly but doesn't link.
