Fix up bumpversion to work with our version numbers
Fix up bumpversion to work with our version numbers

You can now do...
$ bumpversion [year|month|minor|patch]

Versions that are not based upon a new style guide would always be done
using:
$ bumpversion patch

I have disabled automatic tag creation since it seems impossible to do
this:
$ bumpversion year month
