Advanced filters

Lovely tool!

One thing that would be nice is to be able to specify additional filter conditions to omit actions/comments under certain conditions.

E.g. (syntax is just a sample)

issues:
  actions:
    enhancement:

      # Only comment with a funding request if it the funded label has not yet been set
      if: !funded

      comment: >
        This has been accepted as an enhancement request. Good job :+1:

It would be nice to also be able to filter whether the issue/PR is just opened or if the label has been added to the existing issue/PR.
