* page-fade:
Remove redundant 'background-image' PNG fallback for
IE6-8 in '#mw-page-base' because the vertical-gradient() already
creates a solid fallback color which seems good enough for IE6-8.
Remove the 'background-color' rule which was only there to fill
the gap above the the IE6-8 PNG image fallback, which in turn
overrode the background-color rule from vertical-gradient.
The background-repeat rule is also redundant with background-image
gone.
* watch-icon-loading:
This is only used when the JS code is active and the user
clicks the watch star. It does not need a PNG fallback, as it
is only needed in Grade A browsers where the JS executes,
which are expected to support SVG.
Also removed the embedding as the rendering of article text
on page load should not be delayed by an icon that might
be used if and when the user clicks on the watchstar (and
irrelevant to logged-out users).
