Missing Layout properties in the editor

[labordep]

Rename "STLayout" to "Proportional" in the editor view.

Additionally, include all properties such as offset (left, right, bottom, top) and proportion (left, right, bottom, top). May be others ?

@Nyan11 thanks for the list. Initially I wrote this issue just for missing ProportionalLayout stuff for alpha4. No problem to process others layouts, I will rename the issue.
