Media tunneling may be not supported by more devices than the ones we
whitelisted before.
As a matter of fact, the list of devices on which media tunneling is disabled
could be not maintainable in the future, especially if the list of devices
grows more and more.
A preferable solution is to allow users to configure this setting themselves,
allowing them to not wait for their device(s) to be whitelisted in a future
NewPipe update.
This solution has been applied in this commit and works on every build type.
The corresponding preference in the debug settings has been of course removed
and the code used to prevent media tunneling activation on specific devices has
been removed.
- remove duplicated string (name) and avoid potential duplicate (autoplay_never_description -> Never, autoplay_always_description -> Always because they are just "Always" or "Never"). Fixes#4268
- leakCanary string removed (fixes#4233)
Before, the direct value was given to the user, now it uses the parsed
date so we can match the device's language.
To get the relative time from the parsed dates, we use the PrettyTime
library.
Also introduces a debug option to check the service's original value.
