Michael Natterer 539927ebfa app: replace all g_assert() by the newly added gimp_assert() 
which is just a #define to g_assert for now, but can now easily be
turned into something that does some nicer debugging using our new
stack trace infrastructure. This commit also reverts all constructed()
functions to use assert again.
