Subject: [PATCH 1/2] Change python version check

Hello,

I run neovim without python2 support, currently without setting `g:gundo_prefer_python3` I get an error regarding the import of the neovim module (to be expected), this removes the need to set the above mentioned variable when running with only python3 support, while otherwise keeping the same default behaviour.

Cheers, and thank you for creating such an awesome plugin.

 Nathaniel

Subject: [PATCH 2/2] Remove additional 'g:gundo_prefer_python3' checks

These check are no longer needed, we will either have python, or python3, or have thrown an error and finished.
