Changelog:
2014.10.21:
- Increased the max output packet size for "MultiFramedRTPSink" and "RTCPInstance" from 1448
  to 1456, because we had a report of problems when proxying incoming JPEG/RTP packets of this
  size (and because 1456 bytes still gives a packet size of no more than 1500 bytes when we add
  in IP, UDP, and UMTP headers).
Merge pull request #33 from lshl/master
