Reasoning:
Extrapolating from some issues and questions, users tend to want to delete old keys if they create a new one. And others requested a feature to disable certificates because they don't want them to clutter up their keyring.
We want to be able to tell users that they should keep their old keys (to decrypt old data) but don't have to see them if they mark them "disabled".
Therefore we need the following changes:
- The filter "All Certificates" should show all certificates/keys except the disabled ones.
- All other filters where this applies should be changed accordingly (should be all except the X509 ones)
- All tool tips of these filters should get the addition " (except disabled ones)" (and work on T7300 at the same time)
- Add a new filter "Disabled Certificates"
