Apply Scale for Empties

It is now possible to use "Apply Scale" for Empties. While Empties don't exactly
have any Object data attached to them which can be used for supporting "true"
apply scale (i.e. with non-uniform scaling), they do have a drawsize value which
controls how large the empties are drawn (before scaling). This works by taking
the scale factor on the most-scaled axis, and combines this with the existing
empty drawsize to maintain the correct dimensions on that axis at least.

Core Assumptions:
1) Most scaled empties have uniform scaling anyways (i.e. most empties used for
bone shapes)
2) On balance, preserving non-uniform scaling of empties after apply scale is
not as important as not being able to do it at all
