Don't include the root element when calling Element#getElementsByTagNameNS.
Follow-up to work done in #4304.

all_elements should ignore root as well.

Update PowerMeasure.py post-cargoify
Groove and Ridge rendering shows a solid border when color is black,
that is broken and the current patch will implement a similar behavior
as Firefox.
Adding tests to check behavior. There are 3 files that will test:
a) If the groove border is different from a black border (the bug that this
patch set fixes);
b) If a ridge border is different from a black border (samething);
c) If groove is different from ridge (they should be inverse of each other).

All 3 new tests passes on OSX Yosemite (10.10).
Restored older behavior for lighter color, should fix
the regression.

layout: Refactor inline layout a bit.
layout: Implement `text-indent` per CSS 2.1 § 16.1.

I had to use a somewhat unconventional method of computing text
indentation (propagating from blocks down to inlines) because of the way
containing blocks are handled in Servo.

(As a side note, neither Gecko nor WebKit correctly handles percentages
in `text-align`, at least incrementally -- i.e. when the percentages are
relative to the viewport and the viewport is resized.)
