The TeplEncoding class has been removed, as part of the beginning of a complete overhaul of the file loading and saving functionality.

Start to rework the TeplFile, TeplFileLoader and TeplFileSaver classes. As such, there are some API breaks in those classes. And as a result, they currently contain less features as before, unfortunately.

The TeplMetadataManager API has been re-worked.

The TeplFileMetadata class has been replaced by TeplMetadata, the latter no longer depends on TeplFile.

The tepl_file_get_file_metadata() function has been removed.

The tepl_tab_load_file() function no longer loads the file metadata (but it was anyway an implementation detail).

The TeplAbstractFactoryVala class has been removed, because it's possible to manually manage GObject references in Vala.
