A few new LUA functions for wciow

[softcoder]

You had asked for registering an area of cells. I looked at how GAE does it and its too different to follow that approach, so i added these:

int registerCellAreaTriggerEventForUnitToLocation(sourceUnit, pos)
int registerCellAreaTriggerEventForFactionToLocation(sourceFaction, pos)

In both cases pos is a 4 value array specifying the 'box' of cells (x,y of top left, and x,y of bottom right).

Thanks

Thanks Softcoder 

I've uploaded my scenario now but I will use these in the next scenario I make
