[PATCH] Changes Assemblers to use Template pattern

[Chris Meyer]

Hi Jon,

Here's the patch. It's just the basic stuff (no class restructuring 
or return value restructuring).

Adds protected methods to Screen, Layout, Page, Navigator called 
'doBuild' which should be overridden in derived classes instead of 
'build'. This allows us to insert useful class-wide behavior in the 
'build' method. The loaders still invoke the 'build' method.

Additionally, in the 'Action' method, renamed 'build' to 'perform' 
and added a 'doPerform' method.

This change is entirely backwards compatible. Code written for the 
old interfaces should continue to work.
