Theme Template Files for Drupal 6

As part of Josh's deal with DmitriG to get him to cover Drupal 6.0's actions and triggers support (see lesson 40), He is going to do a lesson covering the advances in Drupal 6.0's handling of theme templates (those tpl.php files we all know and love).

In short, Drupal 6 brings a lot of the best practices that developed around template files in 5.0, and puts support for them into Drupal Core, as well as implementing a new standard in the core modules that contrib/custom developers can aspire to and emulate. The new omnipresence of template files radically simplifies the process of overriding the output of theme_functions, as well as making things more hospitable to designers.

The objectives for this lesson are to create a good introductory screencast to this concept, and then talk about some advanced functions/use-cases.
