Reduced excessive exception handling in NumberConversions. Addresses BUKKIT-825

This also allows, for instance, to parse complex numbers with imaginary part=0, if the according toString method omits zero components.
This also saves some unboxing (Foo.valueOf returns a wrapper, while Foo.parseFoo returns a primitive)
