This patches several things:

1) brings back complete URL's in Location: headers
2) makes the default "base" into the URI for the mapfile
   rather than ""
3) pointinrect() now can take any two opposing corners in
   any order
4) closes potential for an infinite loop in mod_imap.c
5) if a mapfile isn't found, returns NOT_FOUND instead of SERVER_ERROR.
