Angel / Demon Hunter: ability improvement

[SkullFace]

Proposal:

The Angel / Demon Hunter abilities are reworked to use a drop-down that effectively allows the user to define the radius of the scan, from 1x1 to 3x3 to 5x5 tiles basic (c.f the NC teleport drop downs). The Acute Sensitivity upgrade ability allows for increased ranges out to 7x7 and decreased MP cost from 6 MP to 4 MP.

I can support something like this being implemented.

Maybe this would be a good function for Acute Sensitivity.

Next patch, Acute Sensitivity is getting a toggle between Acute's wider range and the normal unboosted range, which should hopefully help with triangulating.
