Allow Geomancers to nuke with TP

[Alhanelem]

The job already has some unique casting mechanics, I don't think it needs to be further complicated by flipping between TP and MP.

I think the positional and directional nature of the job is going to be enough complication at first without worrying about TP and MP simultaneously. Then again, it doesn't sound like a horrible merit or late-level concept. For now, I'd like to see how the Indicolure and Geocolure trade-off works first before thinking about gaining TP.
