The issue is with "dllexport": previously, dllexport was present on
exposed templates tool (= visibility(default) for gcc/clang). This
ensured MacOS compatibility since then the typeinfo is corretly
shared and dynamic_cast/typeid works.
For Windows, the "dllexport" equivalent requires the template
instantiations to be declared "external" which is a coding nightmare.
The solution is to provide separate macros for real (non-specialized,
not explicitly instantiated) templates (.._PUBLIC_TEMPLATE) which
is defined as empty for Windows and "visiblity(default)" for gcc/clang.
1.) Startup issue:
This is solved by making sure templates with virtual functions
are made visible in the DSO. This way, dynamic_cast is possible
across DSO's.
Scary: clang/MacOS wants the forward declarations be declared visible as well.
2.) Menu issue:
The best solution is to have only one QMenuBar. The navigator
now gets a synthetic menu bar composed of QToolButtons.

This commit also contains some important fixes:
* Option -wd wasn't working
* Relative layout file paths in session files are resolved as relative
to the session file. On writing, absolute paths are used, so this
change only affects session files build intentionally.
Plus:
* Program version is available in unit tests too
* Fixed a typo in the RBA::Expression documentation
The patch is based on splitting the application class into
two incarnations - one for GUI capability and one without.
GSI binding happens dynamically based on the mode chosen.
We can do so because the application class is the first one
to become active and can decide the mode by itself.
In general, the application class carries too much functionality
and splitting is a task for the future. Right now, the functionality
is inside the base class and the derived classes basically only
configure the base class.
A better design would be to drop the QApplication inheritance in
the RBA::Application class hierarchy and provide access to the
QApplication object through qapp_gui getter.
