Signals in the api and the KDevelop:: namespace

[David Nolden]

I've noticed that in iprojectcontroller.h the signals have KDevelop:: prefixed 
in the argument-types:
void projectOpened( KDevelop::IProject* )

While in idocumentcontroller.h the signals look like this:
void documentActivated( IDocument* document )

Since Qt does only do string-matching when connecting signals, these should be 
unified. Either always with KDevelop::, or never.

Would be nice if this could decided fast, because it causes problems in the 
teamwork-plugin and I don't want to make it inconsistent there just to change 
it again later.

greetings, David
