Add rule name to RuleAction logging
With complicated rulesets knowing which rule is responsible for the action

when being executed adding the rule's name to this logline should simplify
understanding and debugging complex rules.
Additionally the mix of string interpolation and formatstrings in Quarantine.pm
got unified to formatstrings.
 Attach is covered via Notify, Disclaimer and ModField could result in too
verbose logging (i.e. users adding many headers to a mail) without any gain
