[Ur] PATCH: -version flags for urweb compiler

[austin seipp]

Damn, sorry for the atrocious formatting of the last email. I'll just
be sure to trust the autoformatting next time instead of second
guessing it.

Also, I neglected to mention the patch is just a simple diff that can
be applied by:

$ patch -p1 < /path/to/compiler_version.patch

(needs -p1 since it was generated by hg and adds someting to the path inside)
