Changed name of project

Have to rename the repo in Github...

This name is better. 'Mythology' is kind
of 'meh' and already taken by some other
stuff on Github.
Stub for content builder tool

I hate editing JSON. I am going to make a
simple tool that just uses templates for
skills / equipment / whatever and just appends
to everything.json. This way I can build up
a lot of sample content quickly.

This commit is a stub. A real script will come
later.
Stub for addContent method

This is a stub.
