Zone definition components

[Laupetin]

Working with mods that include multiple larger assets like weapons I noticed that it cludders the asset folders quite a lot.
For example when having multiple weapons in a mod it makes it hard to recognize which materials belong to which weapon.

I therefore want to add a "component" system that makes it possible to easily split assets in different components.
The way I currently planning this to work is to make it possible to specify component,name_of_component in a .zone file.

It then looks for components/name_of_component/(zone_source)/name_of_component.zone in the source search path.
If it was possible to open and load this file, components/name_of_component is added to the asset search path and the .zone file is included.
