The initial patch has been reviewed at the issue page. This commit also
fixes template_renderer_factory::get_renderer() and sets up folders for
subtypes there.
Also, part of the change from weblib.php functions to $OUTPUT-> methods.

This is a big change, and the result is not perfect yet. Expect some debugging output
on some pages.
The main part of these changes are that $OUTPUT->header now looks for a file
in the theme called layout.php, rather than header.html and footer.html. Also
you can have special templates for certain pages like layout-home.php. There is
fallback code for Moodle 1.9 themes, so they still work.
A few of the old arguments to print_header are no longer supported. (You get an
exception if you try to use them.) Sam H will be cleaning those up.
All the weblib functions that have been replaced with $OUTPUT-> have version in
deprecatedlib, so existing code will go on working for the foreseeable future.
This is part of http://docs.moodle.org/en/Development:Theme_engines_for_Moodle%3F
The concept is that all the print_... functions in weblib get replaced by methods
on a moodle_core_renderer class. Then, the theme can choose whether to
use the standard moodle_core_renderer class, or another implemenatation of
its own choosing, to generate different HTML.
Also, becuase Moodle is modular, we may need a moodle_mod_forum_renderer
and so on.
In order for the theme to be able to choose which renderers get created, we
introduce the concept of a renderer factory, as in the factory design pattern.
The theme will choose which factory should be used, and that then creates
the renderer objects based on the module name.
This commit includes 4 types of factory:
* standard_renderer_factory
* custom_corners_renderer_factory
* theme_overridden_renderer_factory
* template_renderer_factory
All this with unit tests and PHP doc comments.
Note, this new code is not actually used yet. Still todo:
1. actually define the moodle_core_renderer class, and deprecate a lot of weblib functions.
2. make theme_setup initialise everything, so it is used.
