Resolved the dependencies between MainWindow, TechController
and MacroController somewhat more.
* The macro controller now listens to the tech controller
for the active technology
* The tech controller has more responsibility now
* Some functionality has been taken out of the MainWindow
and put into the controller's implementation
* Introduced "refresh" method of tech setup dialog
* Some refactoring -> tech management is part of
tech controller
* Macro category management moved to macro controller
The respective new classes are RBA::Technology and
RBA::TechnologyComponent. This interface will replace
the current way of doing tech management from scripts
by using the "technology-data" configuration parameter.
