This makes the class API a bit more sane, although
only a bit, because I had to leave it working with
possibly new code merged in from LL: the API can't
really change. I also removed some unused code.
While reviewing how LLFrameTimer worked however,
I did find a few instances where things where broken:
* sFrameDeltaTime wasn't correctly updated (more
than once per frame and therefore erratic). This
only influenced scrolling speed, but still.
* While dragging an inventory item, the scroll
arrows of a tab container didn't work
(LLTabContainer::handleDragAndDrop).
* Map zoom interpolation was broken (it interpolated
between A and B, but used the already updated
interpolation for A the next frame...
(added mCurZoomValInterpolationStart).
Remove erroneously linked control variable.
The 'value' of a LLFlyoutButton is the (last) selected value:
a string. Linking it to some random boolean control variable
causes this value to be (re)assigned to the flyout button list
through LLControlVariable::setValue (whenever said boolean
changes, in this case when the floater is made to appear)
which calls getComparableValue with the string value (ie "mute list")
and tries to convert that to a boolean. Obviously That fails
and the value is set to "", effectively having nothing selected
anymore.
This fixes

-Required addition of an extra texture overlay for list headers, as normal button overlay is used for sort arrows.
-Added padding to italic text in scroll list, as the text clipped outside of the element.
-Groups list is now sortable and has header visible.
-'none' entry always be first in the list, regardless of sort order.
-LLGroupMgrGroupData::mListInProfile removed. Was unreferenced and always false. LLGroupMgrGroupData doesn't handle show/chat/notify properties
