* Improved export error handling, streamlined ExportFailed

* Cleaned out export related visibility in Session, and simpified Session <--> export component communication in general
* Removed export_status.h header dependency from session.h
* Added check for libsndfile FLAC and Ogg Vorbis compatibility
* Added ExportFileFactory, leading in cleaner code in ExportProcessor, and better extensibility for possible future non-libsndfile formats
