PCL Transformation

I have updated the project type to support the Portable Class Library targets.  There were some instances where constant names were different (i.e. Timeout.InfinteTimeSpan versus Timeout.Infinite) as well as some culture settings (i.e. CultureInfo.InvariantCultureIgnoreCase).

I added a sample console application as well to test out basic features against my Boot2Docker instance.  You may want to take a look at the X509Certificate implementation as PCL doesn't support System.Security.Cryptography at all.  I was able to find another library that handled that though.

If you have any questions/concerns, just let me know.  Thanks!
