Catching exceptions in Qt virtual methods

• Added stop as an alias for stopForInteraction (#10, thanks @itghisi)
• Now exceptions raised in virtual methods make tests fail, instead of silently passing (#11). If an exception is raised, the test will fail and it exceptions that happened inside virtual calls will be printed as such:

E           Failed: Qt exceptions in virtual methods:
E           ________________________________________________________________________________
E             File "x:\pytest-qt\pytestqt\_tests\test_exceptions.py", line 14, in event
E               raise ValueError('mistakes were made')
E
E           ValueError: mistakes were made
