Changes from 13/12/2014.

Changelog:
2014.12.13:
- Updated the H.264/H.265 parsing code in "H264or5VideoStreamFramer" to be a little smarter about
  how it computes a file's frame rate (when streaming a 'raw' H.264 or H.265 file).
  (Thanks to Michel Promonet for inspiring this.)
- Updated "config.iphoneos" to work with the latest Xcode.
