Fixed up Tipping

Appears to be working well cross planet.

Working:
/tip name 1000
/tip 1000 (with target)
/tip name 1000 bank
/tip 1000 bank (with target)

Not 100% sure how tipping worked in NGE, but currently 'target' is passed into the function as the current mouseover target. /tip 1000 if you only have somebody targeted (but not moused over) fails to tip.
