-Floater utilizes a slightly modified LLPanelNearbyMedia, which has fading and the 'minimal' mode disabled when its parent is a floater.
-Due to how LL designed LLPanelNearbyMedia, only one instance should ever be allowed at a time.
Added LLNameBox. To avoid having dupilcate code, logic in LLTextBox::fromXML had to be moved to LLTextBox::initFromXML.
-Perfomed some additional cleanup. 'name' attribute now parsed in LLUICtrl::initFromXML, or as-needed for elements not based off of LLUICtrl.
LLSlider now respects current DrawContext
Fixed the AO toolbar widget reserving too much width.
Made the "wlfAdvSettingsPopup" setting persist, and un-inverted its logic.
Altered ui initilization order. Toolbar/overlay panels now constructed further into login process.
