This required some changes to the framework:
* Init-/DeInitVCL is no longer done per individual test in BootstrapFixture, but
once per CppunitTest invocation in a new vclbootstrapprotector (similarly to
the exisiting unobootstrapprotector). CppunitTests that need VCL now need to
declare gb_CppunitTest_use_vcl.
* For things to work properly, the UNO component context needs to be disposed
from within DeInitVCL (cf. Desktop's Application::DeInit called from
DeInitVCL). The easiest solution was to introduce an
Application::setDeInitHook (where the hook is called from DeInitVCL)
specifically for vclbootstrapprotector to call.
* PythonTests don't (yet) call DeInitVCL; they still hook into
BootstrapFixture's original test_init functionality (to call InitVCL), and do
not make use of the vclbootstrapprotector.
