Turn on indent in vim for git commit messages.

I have added the line `filetype indent plugin on` to my .vimrc so that
it will wrap lines at the proper 72 charcters. Horray. Previously I was
manually wrapping at ~72 chars 'like an animal!'.
Add more aliases to gitconfig.

Added aliases for `tags -l` to list tags, `remote -v` to show all remote
info and `branch -a` to show all branches local and remote.
Removed SVN_EDITOR and GIT_EDITOR variables.

Removed definition of SVN_EDITOR and GIT_EDITOR changed only the EDITOR
variable to use vim. I want to start writing my commit messages in vim
so I get a bit more vim info, also I don't want to launch emacs with all
my setup when I want to make a quick commit.
Add Gtags to emacs. Whitespace cleanup in git config.

Added gtags to be autoinstalled with my emacs setup. Added the automatic
whitespace cleanup in .gitconfig.
Add .profile. Removed SVN_EDITOR GIT_EDITOR.

Added .profile to load my .bashrc when running under a login shell.
Removed commented SVN_EDITOR and GIT_EDITOR definitions.
