Moves non-interactive settings to top of profile
Adds bashrc settings to bash_profile

~/.bashrc is the correct place for interactive settings.  Unfortunately,
`bash` is inconsistent across platforms/distributions as to whether it
will source ~/.bashrc.  So, use ~/.bash_profile, but don't run
interactive settings unnecessarily.
Removes .profile (only use .bash_profile)
(whitespace) changes tabs to spaces in bash_profile
Adds pairing station "driver" functions
Updates driver function to make more sense

More natural to call `driver {alias}` than `me {alias}`.  Moves logic
into driver function, and makes `me` an alias for `driver`.
Uses better names for driver functions

Shells don't generally have a concept of namespaces, so it's often nice
to keep things together by using a common naming prefix.  Switch the
driver()-related functions to be driver_{something}, and the git-related
function to git_{something}.
Rewrites driver function to handle more commands

Organizes the control-flow of driver() to be less "case"-y.  Splits some
functionality into separate driver_{something} functions.  Adds some
better defaults.
