Title: Def ctor for knob + logscale patch

This contains two things. I am sorry, but I accidently merged these two. The patch contains:

* Default ctor version for knob class
* Extensions for knob (requested by @diizy)
* QColors depointerized (requested by @tobydox)
* Logscale Patch, including fix suggestions by @tobydox

The patch contains two minor bugs: Stereo linking does not work for logscale connections (@tobydox promised to fix this) and the pointer in the automation window always shows linear values to the user.
