Windows8 Store Apps Support

This release provides basic support for Windows 8 Store Apps platform. Also, there are a lot of bug fixes, specially regarding some validation checks on connection before performing some operations.

There is a huge improvement regarding socks operations. Matter fact, now you can use the connection id (returned by connect method) to perform the send and disconnect operations. This can make things easier when building a wrapper in your app or when managing your connections.
