This adds a new setting to the Settings page.
Existing enclosures and images will be moved to the new location
(first copied, then deleted in the original location). If any of
the copy actions fail, the operation is aborted and the original
path is restored.
The StorageMoveJob is set up in such a way that it's easy to add other
files or subfolders in the future.
Solves #15
For now this only works with NetworkManager. The related settings are
greyed out on systems not using NetworkManager.
Some details of the implementation:
- Implement settings in the settings menu to enable/disable feed
updates, episode downloads and/ or image downloads on metered
connections. If the option(s) is disabled, an overlay dialog is shown
with options to "not allow", "allow once", or "allow always".
- If the network is down, no attempt is made to download images and the
fallback image will be used until the network is up again.
This also solves an issue where the application hangs when the network
is down and feed images have not been cached yet.
- Next to this, part of the cachedImage implementation in Entry and Feed
has been refactored to re-use code as part of the image() method in
Fetcher.
- In case something unexpected happens, an error will be logged.
- This refactoring also includes a cleanup of a lot of header includes to
avoid circular dependencies.
- The error message will now be shown below the info message.
- Add database migration (for Errors)
Both classes are based on classes taken from Elisa.
The audiomanager class will be adapted to add functionality like saving
and restoring play positions and interfacing with MPRIS2.
