Get rid of the forward..Signal() methods [patch ready]

[diederik]

KMess has some forward...() methods when a class only needs to relay a signal. It appears Qt has a better way to write this, like:

connect( object, SIGNAL(..), this, SIGNAL(..) );

In other words, the signal can be connected to the next signal instead. Sometimes the forward methods have some useful debugging information, so it's not needed to rewrite those. The others however, could be rewritten.

Fixed.

Some more could have been deleted, but I was unsure if calling something like:

SIGNAL( slotItemExecuted( contactListView_->currentItem() ) )

would have worked or not.. If it's interpreted at preprocessing time, it won't, so I preferred to leave such calls. However, I've replaced a forward method with this:

SIGNAL( moveToGroup( group_ ) )

Since at that point in the code group_ is always set, there should be no problems with that.. Am I right? :P

Removes slots which just send a signal.

Fixed with r3131. Two of the classes in that kmess-1.5 patch do not exist anymore.
