Bump vim-fugitive
switch to "offical" autotag repository

This appears to be the official repository for vim-autotag

https://github.com/craigemery/vim-autotag.git

The individual script can be found at:

https://github.com/craigemery/dotFiles/commits/master/vim/plugin/autotag.vim
Remove autotag submodule

The official repository isn't so up to date, and the owner hasn't
migrated all of the code yet:

https://github.com/craigemery/vim-autotag.git

His script is up to date so going to move to that.
