- put file name in Sqlite connect string in quotes
- improvements to Mediatek Philips 120+125/Sony serializer (physically reorder XML nodes, use flags stored in Java serialized blob)
- selecting a RefList changed the current working directory, which prevented .ini files to be found by loaders
- SignalSource.IP is now treated as a broadcast system (distinguishing Analog/Dvb/Ip) and no longer a broadcast medium (like antenna/cable/sat).
- SignalSource.Digital was renamed to DVB
- added "Pooling=False" parameter to all Sqlite connection strings to prevent open file locks after closing the connection and to avoid extreme delays when using CloseAllPools()
- C# code refactoring "using var" instead of "using ( ) { }" where possible
- fixed issues where SQLite database files didn't get unlocked after saving
- fixed quirks with missing e_sqlite3.dll when running unit tests with Resharper
- replaced misuse of "FileLoadException" with a custom LoaderException to handle file loading issues with better continue/fail logic
- removed "Save As" and replaced it with "Convert list" menu item that shows information on how to use a reference list instead of direct conversion
- added round-trip unit test for all loaders to check reordering channels and favorites, saving and reloading
- internal code clean-up regarding different favorite list modes (none vs. flags vs. ordered per source vs. mixed source)
