git: Add a version-bump command

Use like:

    git add setup.py  # Bumped version
    git version-bump 0.1.2

If a `get-version` command exists, the `version-bump` command will use
that to get the current version:

    git config --local alias.get-version 'cat VERSION'

    echo '0.1.2' > VERSION
    git version-bump
tmux: various tweaks

* Add PREFIX < for pane-to-the-left, PREFIX + for pane-above
* Fix problem with MPD track display
* Grab the DISPLAY variable when attaching to a session
vim: Unset background, instead of black background
vim: Fix python integration
vim: Do not jump to last used line in git commit messages

It ended up with you editing somewhere in the explanitory commit, which
is not useful.

vim: Disable jedi-vim autoconfiguration

It set some options that I did not like.
