[self-interest] Modules and trees basic howto

[Russell Allen]

As a follow up, I’ve pushed a change to the worldBuilder.self startup script which adds a new flag, -b (for ‘base’) pointing to the base (i.e. a replacement for SELF_WORKING_DIR). This makes the procedure:

> mkdir self ; cd self ; git clone git at github.com:russellallen/self.git ; cd ..
> git init myproj ; cd myproj 
> Self -f path/to/self/objects/worldbuilder.self -b path/to/self/objects

Nice and simple :)
