Improved logic for moving insertion point across hidden text,
allowing for hidding entire blocks, both via the display:none
property, and using the collapse()/isCollapsed() mechanism.
added several new functions to fl_ContainerLayout:
bool canContainPoint()
virtual bool _canContainPoint()
setVisibility(...)
isHidden(...)
In addition I have replaced most of the separate calls in FV_View of
the type
pBlock = _findBlockAtPos();
pRun = pBlock->findPointCoords();
with _findPositionCoords(). The reason for this is that the latter
handles hidden blocks. I have also added const qualifiers to several
functions in the FV_View class.

fv_View*.cpp, ap_EditMethods.cpp
