Merge inspectors UI project, gooey-4, into viewer-2 trunk. Added new tooltips to 3D avatars, 2D avatar names, and 3D objects. Refactors tooltips and text boxes, line editors, and text editors. Breaks LLExpandableTextBox, but a fix is coming.
Resolved conflicts in lltexteditor.cpp, llchatitemscontainerctrl.cpp, llchatmsgbox.cpp, llfloaterbuycurrency.cpp, llnearbychat.cpp, floater_buy_currency.xml, and ru/strings.xml
Merging revisions 134925-135157 of svn+ssh://svn.lindenlab.com/svn/linden/branches/gooey/gooey-4 into C:\source\viewer-2.0.0-3, respecting ancestry
