Move stream operator from AppEnum header

This PR will reduce the compile time of code using AppEnum. 

* AppEnum: Move QTextStream operator to avoid include of QTextStream
* Avoid use of iostream in cafAssert
rator to avoid include of QTextStream

Include file profiling shows that include of QTextStream is a performance issue. Create a non-templated base class for AppEnum. Implement the QTextStream operator for this interface.
