Added Gzip support

Browse Source 
Summary:
Added Gzip function to RCTUtils. This uses dlopen to load the zlib library at runtime so there's no need to link it into your project.

The main reason for this feature is to support gzipping of HTTP request bodies. Now, if you add 'Content-Encoding:gzip' to your request headers when using XMLHttpRequest, your request body will be automatically gzipped on the native side before sending.

(Note: Gzip decoding of *response* bodies is handled automatically by iOS, and was already available).
