* lang/qt/src/cryptoconfig.cpp: New.
* lang/qt/src/cryptoconfig.h (CryptoConfigEntry::stringValueList):
New.

This is a pardigm change in cryptoconfig.h to avoid ABI breaks
with each new config value we support it now has an implementation
that is directly related to qgpgmenewcryptoconfig, which is now
the only one.
