pull in upstream changes but keep base sdk at iphoneos4.0
update SDKROOT to iphoneos4.2
Added SeriouslyDemo, a demo iPhone app to show how to use Seriously.
Removed dependency on SeriouslyJSON from SeriouslyOperation. Leave the decisions up to the caller.
Split parser specific files into thier own static lib. update the demo project to build the two libs instead of including the source.
XCode added some comments to the Demo project.pbxproj
Added SeriouslyOAuthOperation functionality

Overrode the (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
method in SeriouslyOperation to continue without credentials for OAuth operations where the authentication should already be in the
headers.
formatted blocks in SeriouslyDemo
Don't mess with the request in the requestOauth method, apparently it's signed or something ;-P
release _urlRequest in dealloc because it is retained in initWithRequest:
update .gitignore for xcode4
change SDKROOT to Latest iOS
updated SeriouslyDemo project to use xcode4's build directory for the header search path
update SeriouslyOAuthOperation to use NSURLRequest instead of NSMutableURLRequest

An OAuth request should come in signed, and not be modified. Forcing the use of
NSURLRequest should prevent modifications.
