Manual filter rules
please add support for manual filter rules, eventually by adding an option [ ] Apply automatically to new mails for every rule.
There already is some Message->Apply Filters which would trigger those filters that are not run automatically, while I'm not sure what the reason currently could be for failed filter rules.
Background: I don't like automatic filter rules that are run on my single client. Working with different clients those filters are not applied if the single Evolution client is offline at the time of arrival. Server rules would solve that, but this is a different discussion about how to edit server rules from clients via SIEVE scripts etc. However when working with evolution I still need to do some work like moving mails that can be automated and I would prefer just to call "Apply rules" via shortcut on the currently selected mail.
