[Mono-list] IntegerFormatterTest

[Nick Drochak]

Gonzalo,

The test for IntegerFormatter isn't an NUnit test, so it doesn't really
belong in corlib_test.dll right now.  Including it in RunTest.corlib.exe
breaks the build because there are two Main() entry points.  Also, including
it in the corlib_reference.dll test won't work because IntegerFormatter is
not public in the mscorlib.

I updated CVS to fix the build problems, but really this needs to be an
NUnit test.  Can you change it into one?
