Subject: [PATCH] vim: use tpope's :Ggrep over home-rolled :GitGrep, update mappings

My GitGrep served me very well over the years, but tpope added :Ggrep to
fugitive, and, well, his is of course more robust and more clever!

This commit removes my home-rolled solution in favor of the fugitive
plugin.

Additionally, two mapping changes:

1) inoremap <C-U> to save in the undo chain
2) Remove arrow key mappings -- these were throwing other vimmer's off
   when they used my setup!
