Move tests to Tests

* I have moved the testing commands to Kerkerkruip Tests, where they
belong.
* First implementation of a "grantme" command that grants a power --
except that it doesn't work when you try to fill in the name of a power.
Don't know why yet.
Fixed fanatics power.

I noticed that the Fanatics of Aite power didn't have a power text when
you clicked it. Well... turned out someone typed "fantatics". Don't you
hate how easy it is in Inform to create new objects? :)
