bwilkins/user config migration

## user config migration
Context: Using multiple machines in different locations,
where it is infeasible to to have ldap or networked user login etc.
Primarily Unix.

Proposition: One should have a config tool that can import all their
preferences/aliases/configs, and keep such information up to date.
Easy to use a version control system or a database to handle updates etc.
Perhaps extend to create a virtual environment, complete with
tools/applications needed or preferred by the user.

Limits: Total size of environment data should be minimal,
thus serving low-bandwidth situations. Modifiable, obviously.
