resource.
- Bugfix: A segfault would occur if messagetables were parsed without
  memory options attached. Also added buffer-overflow safeguard while
  converting between byteorders.
- Finished remapping usertype resources onto standars types by tricking
  the parser into accepting a different token. The remapping can be
  disabled with a new commandline option '-m'.
- Resolved some warning about chars used as index on SGI O2 machine
  (the ctype isXXX() routines are macros there).
