[development] Changes to capitalization

[Khalid B]

When I first started using and developing for Drupal, the all lower case thing
bothered me, but not too much. Later I got used to it as a Drupalism.

I am all for changing that, but a code freeze is not the time to do it. Also
remember that contribs have to catch up otherwise sites will look ugly and
inconsistent.

Can we also get feedback from the usability folks on this (Laura? Trae?
others?)
