* Auto trust new signal identities
from signald doku: when a remote key changes, set trust level to TRUSTED_UNVERIFIED instead of UNTRUSTED
I find it much more convenient when new identities are automatically recognized as trusted, as the process to do that manually is cumbersome.
Should this the default behavior, or should i add an option to configure this behavior?
* Added option to trust new signal identities
* Using env file
* Renamed variable
* Corrected typo
* Use fully-qualified Ansible module name
* removed option trust_new_keys
