Bumped version.

Moved pathname.rb from ruby 1.9.2 into project in order to continue compatibility to 1.9.3 where
the functionality has been moved into c. In the c version of the file, the unset_const trick
doesn't work because the constant rb_cFile in the c file is never modified. I think this is
actually a bug in how ruby MRI operates, but the fix is a little bit complicated.
