PCK's NSURLConnections can now perform synchronous network requests

Fixed a minor compilation issue with OS X.
UIWebView no longer stubs out initWithFrame

Stubbing out initWithFrame leads to a whole host of issues including:
- crashes when reload and stopLoading are called
- the need to fake out all properties, including ones that we'd get for free
- the need to set up fake properties with values that are consistent with UIWebView's values

Allowing the UIWebView to actually *be* a UIWebView appears to solve all these problems
and does not introduce any new ones...
All NSURLConnections can be fetched synchronously

Added a class method to allow all pending
NSURLConnections to be fetched synchronously.
Any new requests generated as a result of the
fetch are also fetched.
