Loads all settings from other template(s) specified by a section's
'extends' setting.
This method walks a dependency tree of sections from bottom up. Each
step is a group of settings for a section in the form of a dictionary.
A 'master' dictionary is updated with the settings at each step. This
causes the next group of settings to override the previous, and so on.
The 'section_name' settings are at the top of the dependency tree.
