2.1.1 is released!

This is primarily a bugfix release—several bugs were found in the UTF-8 and
internationalization support (thanks Marco Thill!), plus I found one or two
other errors with variable handling (this was a mistake I added back when I
added all the OpenBSD compiler fixes) and un-abbreviated integers. With luck,
this version should last a while, knock on wood.

In other news, Wcalc is listed on MPFR's web page!

Anyway, enjoy -- if you find any bugs, please let me know.
