CI Builds lack `sndfile.framework` and `freetype.framework`

[adammw]

When downloading http://openskyscraper.org/binaries/openskyscraper-20140816-1202-184b5d6-macosx.tar.bz2 and trying to execute it, I get an error that libraries cannot be found:

dyld: Library not loaded: @executable_path/../Frameworks/sndfile.framework/Versions/A/sndfile
  Referenced from: /Users/adam/Downloads/OpenSkyscraper.app/Contents/Frameworks/../MacOS/../Frameworks/sfml-audio.framework/Versions/A/sfml-audio
  Reason: image not found
Trace/BPT trap: 5

Downloading SFML and copying sndfile.framework and freetype.framework from extlibs to the Frameworks folder solves the issue.

I'll fix that in the build script ASAP. Thanks :)!

I get this error too (with my game programs), is it sorted?

[fabianschuiki]

It happens because SFML has a dependency on sndfile and freetype on Mac OS X. Currently you need to manually copy these Frameworks, e.g. from the SFML distribution's extlibs directory, into OpenSkyscraper.app/Contents/Frameworks/.

@fabianschuiki Should the README file be updated to reflect this?
