Added 'NearbyMedia' floater (accessable via new button in Media Remote popup)

-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.
