Readded level handling

Things done:

Wrote a entity:give_experience function (lua side only).
Renamed characterpoints to attributepoints (no db update. Did not want
to do one for a simple rename).
Temponary introduced a ATTR_LEVEL constant. TODO: dehardcode this.
Script binds for settings the correction and attribute points.
