certs: more filters, better initial uid selection, code cosmetics

    - add three types of filters for certificate list (ui looks like crap
      there, need to work on that)
    - select uncertified uids by default in CertifyKeyActivity
    - move some code around in KeychainProvider, 's slightly less hacky now
