[PATCH] RFC: KButtonGroup non-exclusive mode

[Marco Gulino]

Hi all!
While i was hacking KMobileTools configuration dialogs i noticed that there's 
no way (or at least.. not an easy way) to let kconfig_xt manage an OR-ed 
flags int item, like QButtonGroup did in qt3/kde3.
Pino Toscano pointed me to the KButtonGroup class, which is able to manage 
QRadioButtons, but i needed something more generic.. so i hacked on it, and 
with my patch make it able to:
	- Handle QAbstractButtons instead of QRadioButtons only
	- Have a exclusive flag: in exclusive mode the behaviour is the old one (then 
it's the default) while in non-exclusive mode selected() returns the OR of 
the IDs of the selected buttons, and setSelected(int ID) select an AND 
between buttons and ID.
	- Add a setId method to set non-consecutive IDs (very useful in non-exclusive 
mode, but it can be used in exclusive too).

The patch is attached in the message.
Comments?
