FLUID-4698: setting font-size on html

Modified the textSize enactor to set the font-size on the root element (html) instead of the container (body). This will allow support of rem units. Another change with this was to set the value in px instead of ems. This is necessary since the root element has no parent for which to base it's value on. The unit tests have been updated.
FLUID-4698: fixed whitespace issue
FLLUID-4698: Textsize set on correct html now

Fixed an issue where the text size would always be set on the parent document. This was causing issues with the separated panel which uses an iframe for the controls and has its own enactors. Also made another small modification that ensures the multiplier used is always a legitimate value.

FLUID-5320: Simplified getLineHeight and tests

Simplified the getLineHeight to just return the value from jQuery's css method. Refactored the tests to test for the multiplier in IE8 and IE9 and to test for pixel values elsewhere.

Renamed to getLineHeightMultiplier
FLUID-5323: explicitly made jqUnit global

In IE 8, the global jqUnit object was being reset to an empty object when jqUnit-browser.js was added to a page. It seems that this may have been due to an interaction with fluid.registerNamespace.
FLUID-5323: Fixed builder munging tests.

Fixed the builder munging test, which was failing in IE 8, by making it a straight listener instead of using a listener maker.

FLUID-5334: clearing iframe animation queue

Clearing the iframe's jQuery animation queue when the panel is hidden. Previously it could get into a state where the sizing animation would complete after hiding, causing it to appear "open".
