Logic of selecting "full crypt" code:
a) default behaviour:
- dummy crypt code when compiling UnZipSFX stub, to minimize size
- full crypt code when used to compile Zip, UnZip and fUnZip
b) USE_CRYPT defined:
- always full crypt code
c) NO_CRYPT defined:
- never full crypt code
NO_CRYPT takes precedence over USE_CRYPT
