Jean-Marc Lasgouttes 0f15dcc698 Rewrite handling of macro nesting in math rows 
Macro nesting is now recorded into the macro inset itself. This allows
the ArgumentProxy inset to determine whether it is editable or not by
looking at its macro.

Remove code in the metrics and draw methods of ArgumentProxy: this
code is AFAICS not active anymore, since arguments are linearized into
math rows.

Use Changer idiom to change locally the values of MecticsInfo::base.macro_nesting.
