Calculates the distance between two map points (x1,y1) to (x2,y2) and pushes the resulting floating point number to the stack.

#Terrain modification script to build a circular pyramid.
#Keep in mind modifying terrain on a large scale like this can lag the game badly for a short moment, so not recommended to do this mid-level unless you slow the loops.
