Print qCDebugs in arbitrary categories by default

Browse Source 
The debug output of all categories will be visible by default,
except from the "qt.*" categories. "qt.*" categories are private
and their default debug output will be hidden.

[ChangeLog][QtCore][Logging] Enable qCDebug's for all categories except qt one's
