CSS Hero PRO 5.1.0

Automatic data import from V4

Fix: Plugin wasn't working without license key

Two fixes regarding variables. The first one was a short circuit in the is_color function going boom in some weird cases. The second one was related to calculations with vars which should be now ok (@var1:20px; @var2var1*2; –> this caused a bug in the variables panel up to 4.1, fixed in 4.2)
Fix in the beautifier script which now is much more consistent in tab positioning
