Take rootName argument when listing all classes.

Hi all,

Would it be likely to pass a second argument to \generalist command when argument classes is used?

The idea would be to sort the classes without any kind of rootName.

I patched the htmlgenerator.cpp file in order to use the command as follows:
\generatelist

It works as needed. I join the patch. Hope it helps.

Cheers,

Thibaud.
