Title: Signals fixes

Looks like nobody uses signals...

Maybe, because for now it's unusable because if a class have a signal it's impossible for a derived class to have signals ([Issue 8031](http://d.puremagic.com/issues/show_bug.cgi?id=8031)).

With this pull it's impossible for a derived class to have signals only if a base class has the one and only signal (because of [Issue 5028](http://d.puremagic.com/issues/show_bug.cgi?id=5028)) and this isn't a major luck of functionality.
