Please revert a previous change applied to two labels in the edit dialog for a site map entry: set the labels back to their previous values of "Hide" and "Hide children".
MGNLGS-42 asked (among other things) to rename those labels, but also reuqest to change the way the check boxes work. In 5.2 RC1, however, only the labels were changed, but the check boxes still work the same as before: they hide an entry or its children. Since Sasha convinced me in a call that changing the behavior was not as easy as it seemed and would lead to some confusion, we thus agreed to not change the behavior at all.
Please thus change those labels back to "Hide" and "Hide children".
