Entry.inherit, Category.inherit

[fluffy-critter]

A useful function for property getters would be to have .inherit which would be like:

entry.inherit(property_name, default)

which would act like .get except if the value isn't provided on the current entry/category it would walk up the category tree until it finds that value, or falls back to the provided default if not.

This would be useful as a mechanism for storing overrideable template configuration options.
