Extend LookAtController to allow 'upAxis' to be defined.

LookAtController (and by implication HoverController) assumes that up is in the +Y direction. The purpose of this pull request is to allow the up direction to be set by the user of these classes.
Fixed

If i want to know is material have any methods and try do it like this:
getMethodAt(0), i will catch error because of:
ShaderMethodSetup.getMethodAt { return
EffectMethodBase(_methods[index].method); }

It should check _methods length and return null if legnth is 0
