[QBS] Exception in Exception handling

[Jochen Becher]

For the values of a new property "exceptionHandling" I would reserve
"none" for some compiler settings which does disable exception handling
while "default" should omit any compiler option (and thus fall back to
the compiler's default setting).

Regards, Jochen
