Decide how and whether we coordinate our config files

Right now, we have some files in the getting-started/config_files/ directory for coordinating vim colors, VMD hotkeys, and matplotlib style. These can be installed via a make command. Going forward, should we:

- Continue as-is?
- Move to an [/etc/skel](http://www.linfo.org/etc_skel.html) set up for lab machines?
- Remove some of the shared style files but keep others? If so, which ones?

Discuss!
