Fixed wrongly created hierarchies when directly connecting a device to the controlsystem using connectTo(). Now proper virtual submodules are created for each hierarchy level, insted of keeping the slash in the variable name.

fixed connectTo() so it now uses the dynamic/virtual model and thus obeys e.g. eliminated hierarchies etc.

Changed Module::connectTo() to accept also temporary module objects, e.g. as returned by findTag(). As a consequence, the operators [] and () of the modules had to be changed to const.

- allow setting the "eliminateHierarchy" flag in the constructor of a module

This is an interface change which was done in an incompatible way!

added preliminary support for tags to application variables which can be searched for and used to generate virtual modules
