Add Windows environment info collector to the WPF platform

[mgnslndh]

Fixes #290 by add source link to ExceptionslessWindowsEnvironmentInfoCollector in the WPF platform project and registering that services to the dependency resolver.

          You should only need to use the Wpf client, code is shared between the clients. I'm trying to think if there is any reason we shouldn't be capturing that environment info in wpf. I can't think of any reason not to.. Would you mind submitting a pr to add a source link to that file in the wpf project and then adding a line to `client.Configuration.Resolver.Register<IEnvironmentInfoCollector, ExceptionlessWindowsEnvironmentInfoCollector>();` in register.

Not sure why the tests fail because they green on my machine :)

@mgnslndh can you sign the cla, looks like a flakey test we need to look into.

Cloudflare is reporting the clahub as down. Not sure if it is affected by the service outage at Microsoft.

@niemyjski I've signed the CLA. The link was wrong but I've submitted another PR fixing that.
