[Qt5-feedback] More registered types by default...

[BRM]

At least under Qt4.5, the various standard int types - uint8_t, int8_t, etc - 
were not registered with the meta system as far as I can tell, so they are by 
default unusable for signals/slots. I have run into that a couple times as I'd 
like to favor using those over qint8/quint8/etc.  As of VS2010, they are also 
available for MSVC, and providing a definition for MS2008 and earlier should not 
be a problem - just map them to the Qt versions if they are not already defined.

It would be a great benefit in order to aid in making standardized interfaces 
for use with libraries/programs that are not necessarily using Qt.
