Fix git 'upgrade-submodules' alias

Fix implementation to work with git 1.9.0. This version of git
introduced changes that were not backward compatible with older versions
of git, breaking the functionality in upgrade-submodules.

Previous versions of git eval'ed the command string passed to `git
submodule foreach`, but newer versions of git pass the command directly
to the shell.

Change precmds and postcmds from dictionaries to lists. Dictionaries do

potentially lead to bugs if there are commands that are dependent on
order or if there are duplicate commands.
Fix bug in git 'credit' alias

Make git 'credit' alias compatible with shells that do not interpret
hexadecimal escape codes. Use printf instead of echo to produce a tab
character.
Remove extraneous code

Make tmux split windows and panes start in same directory as current

1.9.
