Make currentColor behave the same internally as initial

Make currentColor behave the same internally as initial

While most color properties have an initial value of currentColor,
explicitly specifying currentColor behaves different internally to an
initial value. This patch makes currentColor no longer resolved in style
resolution for properties which are a single color and removes a flag
from RenderStyle indicating that currentColor was explicitly set.

Much more sane to use the same code path, lgtm.
