[Clam-devel] Typed controls

[David García Garzón]

I finally commited the changes needed to have Typed controls working. Thanks 
to Francisco, Hernan and Pau for their work in that nice feature. Still not 
fully working but at least we have done the main merge in a way that old and 
new controls can be used at the same time and that does not affect the upper 
levels. Indeed TypedControls are managed the same than controls. Still testing 
to do on that.

Hernan and me changed Francisco code so that now InControl and TypedIncontrol 
are both subclasses of InControlBase (former BaseTypedInPort). We also 
removed the need of having a separate ControlRegistry for Typed and Float 
controls, so that now old and new style controls can be used in the same 
processing and hopefully used in the network.

In summary:
- Use FloatIn/OutControl to use controls as as now
- Use TypedIn/OutControl to manage them all

TODO's:
* Testing a network with typed connections (it should work but who knows...)
* Supporting not linking incompatible types (the testfarm red, i know, pau)
* Graphical feedback for forbiden connections
* Drawing controls with colors
* Implement some ideas on how to add callback based controls without 
subclassing for every type. (Discussed with Hernan)

Test, make it fail and enjoy ;-)
