Title: Inherit & initial value support for opacity

Hi,

When we give the `initial` or `inherit` keyword value to opacity in nib, it throws an error.

I was thinking that was an error in all the vendor-replacement code, so I had tests to verify the behavior of all the *vendor* properties with `initial`or `inherit` value. ;)
