Support compiling and path search.

- In the hash bang line:
  - use /usr/bin/env to find txr in the PATH.
  - Use new txrlisp hard link, which the file compiler will
    translate to txrvm for compiled code

- Main code is wrapped in (compile-only ...) so that it isn't
  executed during compilation.
