about the menu View -> Unfold math macro

[Uwe Stöhr]

While updating the last part of the documentation for LyX 1.6.0, the UserGuide appendices, I noticed 
two new entries of the view menu: Unfold / Fold math macro
The View menu should only contain general view options. Math macros are special things so in most 
cases these two entries are grayed out and only using space in the menu list. They only have an 
effect for the current macro no all macros, thus they are general settings.

I propose to remove the entries and add the instead to the context menu of 
macros. Opinions?
