src: storage refactoring

* renamed Storage to PersistentStorage
* added Storage as baseclass that implements data injection
* cleaned ParserClient interface
* added default constructors for storage types
* cleaned SqlteStorage by implementing the private getAll methods as template specializations
* added CXX flags to CMakeLists (this is needed for sqlite with visual studio)
* removed TestStorage.h/.cpp since these files were not used anymore.
