New Version 6.0.0

Replaced configuration text files with embedded database, which should positively impact on stability.
Added different options for forcing re-enccoding: Always - re-encode everything, Lazy - no re-encoding for compatible codecs, i.e. alac->aac, vorbis->opus, Auto - re-encode only if codec is different.
Implemented resulting file optimisation - applied at the very end and respect all embed images.
Fixed bug with creating sub-tracks for single source file
Fixed bug with extracting only 1 image from source file, now all artworks are extracted
Added progress for adding artwork and optimising resulting file.
Fixed issue with splitting and combining chapters and parts.
Changed the way presets works - now you need to explicitly save preset instead of confusing autosaving. Also preset now includes all settings on quality tab.
Fixed bug with genres saving
Big number of minor bug fixes
