Eliminated requirement to use -all_load linker flag.

[RCacheaux]

Hi guys,

Thanks so much for this awesome library, our team really enjoys using it.

When we updated our pod dependency from 1.5.3 to 1.5.5, our build broke during linking. I've been able to pinpoint the issue to the -all_load linker flag. There is a known bug with the linker when bringing in categories: http://developer.apple.com/library/mac/#qa/qa2006/qa1490.html

I also found a blog post with more descriptions on the issue:

The blog references a fix RestKit used:
RestKit/RestKit@b96940c

This pull request adds a new macro for embedding a dummy class in all the category implementation files so that the linker can function without the -all_load flag. I built and ran tests for both Mac and iOS.

Looking forward to your feedback!

Cheers,
Rene

@RCacheaux - Thanks for the encouragement! We're really enjoying building Typhoon and are glad that so many other folks are finding it useful.

I noticed the same problem that you observed the other day - when I was (belatedly) updating the sample app for iOS7, and updated the Podspec to include "all_load" flag.

. . however, I didn't verify that this actually fixed the problem. . In any case, I'll go ahead and merge your fix - nice trick, btw.

Thanks!

Jasper

Added the 1.5.7 tag, and pushed to main Spec repo.
