This introduces a new (optional) 'name' field for iconpack icons. It
will be used to describe the icon in the icon selection dialog. If it is
not present, the name of the icon will be derived from the filename,
like before. Using this new field allows usage of more exotic characters
in the icon name that are not allowed in a filename.
This patch replaces the usage of the deprecated FingerprintManager API with
BiometricPrompt. This uses the Android X library, so we get the native biometric
prompt on recent versions of Android and a Google-made one on older versions. By
not working with custom prompts for biometric authentication like we do now, we
can be sure that any issues like #70, #81, #237 are not actually our fault.
Here's what it looks like:
As a nice aside, this also adds support for the new facial recognition as an
authentication method on Pixel 4 phones.
This is still a draft, but early feedback is welcome.
