Removed inclusion of CFRuntime header from class headers that get brought in via #include <SDMMobileDevice/SDMMobileDevice.h> (CFRuntime.h is already included in the "Internal" headers so these includes were unnecessary)
Merge pull request #56 from JeremyAgost/cfruntime-include-cleanup

Make sure CFRuntime.h doesn't get included via <SDMMobileDevice/SDMMobileDevice.h>
