Border Control Still Unreliable

[lankaukk]

The border style section in the inspector was recently fixed, and works correctly on some projects but not in others. cc @liady since you were the one working on this, feel free to tag someone else

yes, since the border actually has a color different than black, so we don't recognize it as a "non-existing" border.

the question is - do we want to treat any 0px border as a "non existent"? This can cause a situation where a user will change the border color (but will leave it at 0px width) - and after reselecting the element they will not see the controller again (since we'll treat it as "no border")
