fix #3287: add recipient filter for virus & attachment quarantines

So that users can filter these quarantine views, e.g. useful if they
have many mails there.

Replaced the emailSelection config with a quarantineType configs
since we want to have different behaviour for different quaratine
types. E.g., we want to show 'all' mails by default for the
virus/attachment quarantine, but not for the spam one.
