[PATCH] adding constant to the operations properties

[Matthieu Sozeau <sozeau club-internet fr>]

This is a little patch to add the constant property to an UML class operation. Although that's not standard UML, i find it usefull for C++ code output and for clarity of the interfaces :). I will add such support to dia2code now.
I was wondering if I could add the final and virtual properties to methods (operations) in the UML module. Perhaps most of users don't want it, so I'm just asking (at lease I'll add it for me).

Note: The patch must be applied in objects/UML as you certainly deduced.
