Title: ignore tags (created by :Helptags when using pathogen)

I use pathogen to deal with the vim plugins, each added as a git submodule. To enable properly the help files, I have Helptags in my vimrc.
This create tags in the doc directory with each plugin, and if tags its not ignored, the submodule results to have (modified content). This should fix it
