Beginning migration to the recommended HttpURLConnection

This will require dropping support for API < 10, if it provides a speed up and better functionality I'll stick with it as Froyo is very very small market share now.
Have migrated MySoup over to HttpURLConnection

Now testing to make sure it actually works properly
Add back in notifications enable/disable redirect handling
Not encoding parameters properly, whoops

Also remove some debug output from private message. PMs don't seem to work on this branch, looking into cause
Fix generic post method by using fixed length streaming mode instead of chunked
Logging out is now functional
Can now get/set cookies

This will be used to save users cookies so that we can use the site without having to re-login, so we can jump easily into any page of the app and not worry about re-logging in. Logging out will invalidate any set cookies.
Error and status checking for the logout function
Some fixes to make cookie handling work properly on Android

I still need to test logging out on Android. Also changing Gson to read from the streams instead of reading in the entire string and then parsing. This should improve memory usage and may help with speed too, I'll test and see.
Some debugging to show folks for questions

This branch won't live long on the public repo and should be ignored
Clean up debug and only return the session cookie
cookieManager could also be null if we aren't logged in
Was returning the auth key instead of the pass key
Merge branch 'feature-better-mysoup' into develop
forgot to include io commons lib
