Hi,

I implement bait and switch pcl trick for PortableFileSystem and now we can use in PCL project directly. and we do not need to initialize for each specific platform project. and fixes #2

Now I can write below code in PCL project:

ConfigurationManager.Initialise(PCLAppConfig.FileSystemStream.PortableStream.Current);
string value = ConfigurationManager.AppSettings["SomeKey"]

Some note:

• I removed your certificate for build project (because your certificate have password and I have not password :D ), so you get back your certificate into project.
