Bugfix #5224

Prob: selection sometimes gave wrong edges/faces

Selection code for editmesh was still using a short for calculating the
distance of a projected vertex/edge/face from the mouse position. In
zoomed in cases that'll give overflows and unpredictable results.

It was fixed only half before... now all shorts are removed for distance
calculus.
