Make UaClientOptions constructor public

[davidmn]

A fix for #64 where by the example code in the README.md did not work.

Before this commit one needed to something like this to get an instance of UaClientOptions:

var dummyClient = new UaClient(new Uri("opc.tcp://host-url"));
var options = dummyClient.Options;
options.UserIdentity = new UserIdentity("username", "password");
using (var client = new UaClient(new Uri("opc.tcp://host-url"), options))
    {
        ...
    }

Which isn't very nice. This was because the constructor for UaClientOptions was internal.

Thanks for this pull request. Please see the appveyor build output. Stylecop gave an error because there are not XML comments on the now publicly visible constructor.

Please see Hyla Soft's CS Boilerplate guide for an explanation of our build system.

Thanks!

I'll get that fixed shortly.

I've added XML and the build passes.
