iOS Framework missing some headers

[jasarien]

Currently the iOS version of Wordnik.framework is missing some headers: WNAdditions.h and WNCompositeWordDataSource.h

I was able to copy WNCompositeWordDataSource.h from the Mac OS version of the framework and into the iOS version, however, the Mac OS version does not seem to have WNAdditions.h either. Luckily, though, WNAdditions.h was located in the Classes directory of the iOS example project. Moving it from there into the framework was sufficient.

Finally, WNAdditions.h did not contain the interface for the NSArray (WNAdditions) category. I was able to judge from the code that the only method implemented in this category was -wn_map:. Adding the following code to the file was sufficient:

@interface NSArray (WNAdditions)

- (NSArray *)wn_map:(id (^)(id obj))block;
