* SSLEepGet, Reseeder:

Browse Source 
- Implement additional CA loading
      - Provide facility to reuse SSL state for speed
      - Provide facility to store previously untrusted certificates
      - Add SSL reseed hosts, prefer them by default
      - Reseed message cleanup
    * build.xml:
      - Add www.cacert.org cert to the installer and updater so
        SSL on a.netdb.i2p2.de and c.netdb.i2p2.de will work
      - Cleanup, fix distclean error in older ants.
