* Added custom audio processor editor for CAR plugin - CAREditor;
* Added buttons to switch between "Reference" and "Affected" channels;
* CAR processor some minor changes;
* Some minor changes in GenericEditor class which provide more
  possibilities for plugins (e.g. plugins can implement their own
  resized() methods, etc.);
* Added UIUtilities header file in which we can include any
  UI components/utilities which will be useful for easier plugin
  creation.

* Since "Small text" renders very bad, without any hinting, we replace
  it by "Default" font.  And also "Default" font is much more suitable
  for Material Design.
* Adjusted font sizes.

0MQ is included, but not linked (unless you define it in
NetworkEvents.h).
Redrawing events are not called for some reason.
