Windows Store support

[phofman]

I needed the Windows Store 8.1 support for this library and since it was not there originally I did the port to PCL. This wasn't extremely hard, but please review my changes and check, if they match your coding style.

Please update the NuGet packages accordingly.

Thanks.

I'll try to have a look when I can, but this project is largely unmaintained now - I'm not doing much work on it, instead concentrating on the proto3 implementation as part of the main protobuf repository (https://github.com/google'protobuf)

Have you signed the Google CLA by the way? I'll need that before I can merge anyway. See https://cla.developers.google.com/about/google-individual

Thanks a lot. I just signed the CLA, but I have no idea, how to export it. I hope you can retrieve it somehow or could instruct me further.

I wish to use proto3, but since C# support is still in alpha there, I was looking here searching for more stable version. For sure I am not going to introduce any new features ;) My changes are mostly around using updated reflection API and missing IConvertible interface. After few tweaks my sample app for Windows Store 8.1 and Windows Phone 8.1 started to work. Let's keep fingers crossed to have it running also after obfuscation and native compilation on Windows 10...

Yup, I've just confirmed that you've signed the CLA :)

You can certainly continue using this version, of course - just don't expect it to be maintained nearly as actively. It'll be on a "best effort" basis - so you should expect to use your own build rather than an updated NuGet package, at least for a significant period. I'll try to get to this at some point though :)
