[development] Theming system, round 2

[Earl Miles]

Hey all;

Hopefully you've seen that I've done a lot of changes to the theming system for 
Drupal 6. I'm not done yet, and I invite help and/or discussion on the next 
wave of things. In particular, the stylesheets topic probably has a lot of 
discussion that it could use.

http://drupal.org/node/141727 => Allow maintenance theme functions to be themable

http://drupal.org/node/141725 => Allow multiple stylesheets in the .info files

http://drupal.org/node/141914 => We need to convert theme functions to 
templates where possible

http://drupal.org/node/141730 => Allow theming system to use wildcards
