Can we change this PR to a wish, "Remove option for changing font style"?
The problem is that Umbrello explicitly sets the style, for example
abstract methods are italicized.

In that case, we need abstract classes (interfaces) to be italicized too -
that's actually why I was trying to make it italics in the first place.

SVN commit 508509 by okellogg:

setInterface(): Set the UMLObject::m_bAbstract flag.
