Code modernising (#8)

* Applied some code conventions, used more current language features which should improve readability and making it easier to re-factor / modify. Also fixed some typos in documentation. * Changes based on PR conversation for the SystemInfo * Some modifications due to conversations on the PR, especially I removed the FlagsAttribute on the BalloonFlags. * Removed Silverlight targeting in code.
