Merge branch 'master' into 'master'

Remove any whitespace from fingerprint EditText input so that copy pasting is easier for users.

Hey,

I just added a line to remove the whitespace from fingerprints when adding a new Repo. Some repositories like https://microg.org have their fingerprint separated with spaces so copy pasting directly from there is more cumbersome if fdroid doesn't remove the whitespace by itself.

Hope it's ok. :)
