Added handling of the wrapped lines case when calculating the starting position for selection.
The bug is a regression caused by the fix of STORM-320 which was dealing with calculating the position of the input cursor while navigating through the lines of text with word wrapping enabled.

This patch makes clipping work consistently with text and embedded widgets. The widgets will only be displayed if the corresponding text they are embedded in is displayed. There is also a new param "clip" for text widgets that can be used to disable clipping entirely. I introduced this as a potential work around due to the fact that we *used* to assume that text was never clipped in the vertical direction unless we had scrolling turned on. This hasn't been the case for over a year, but now we can selectively turn off vertical text clipping with (clip="false") if we have to.
Reason: If some child of transparent LLFloater has a visible non-transparent background then this part of floater is non-transparent. As a result floater became partially transparent.
Solution: When transparent floater changes focus, iterate through its children and set corresponding (corresponding to whether control in active or in inactive floater see STORM-535) transparency value.
- Added method LLUICtrl::getCurrentTransparency. This method calculates transparency level of a control. Calculated value should be used as an alpha chennel value in case we want this control to be transparent. For now this method is used by LLFloater to adjust transparency of its children.
- Added calculating of transparecny level for: LLLineEditor, LLTextBase, LLinventoryListItem, LLScrollContainer, LLScrollListCtrl, LLAccrodionCtrlTab.
- Added method LLFlaoter::updateChildrenTransparency which updates transparency value of its children
LLTextBase::setCursor() sometimes failed to work properly if line wrapping was enabled.
This is a slightly optimized version of the patch made by Satomi Ahn.
