[XForms] fdesign replace menu and formbrowser recompute max_width patches

[SBP]

Hi there!

I include here two patches for your consideration.

The first one fixes a bug wherein replacing a menu item in fdesign
causes a segfault.

The second one recomputes the formbrowser max_width after deletion of a
form. It is consistent to recompute max_width to the maximum of all
form widths, as adding a form sets it this way. I couldn't find another
way to reset max_width, and I need this because I'm resizing forms
inside a formbrowser and I want the scrollbars to match the size of the
form.

Hope you find these useful and they get upstream!
