Fixed determination of WebException
Merge pull request #13 from SeeD-Seifer/master

Fixed determination of WebException
We need the INTERNET permission
Ignore emacs tmp files, and added a couple of explanatory comments.
Removed patch target from PHONies.

This target doesn't exist anymore.
Add Internet permission to HttpClient sample too.

This will make it work under Release profile, avoiding an exception
when sending a request with okhttp.
Merge branch 'xamarin-component' of https://github.com/pupitetris/ModernHttpClient into xamarin-component
