Fix the signature of the Q*Application constructor

Q*Application had PySequence as Parameter, although
only QStringList is accepted. That resulted in an implausible error
message when a list of, say, Integers was given.

This patch
 - replaces PySequence by QStringList (one more tuple layer),
 - fixes QCoreApplication to give the same kind of error messages,
 - renames the shiboken function sequenceToArgcArgv to listToArgcArgv
   and changes it to only allow list descendents.

We also changed signature.typing in one line to display List[str] correctly.

I think this belongs more to PySide-331, a fixed qApp.
