Rename the "DeveloperForce" namespace

[wadewegner]

One thing I never liked about this project was the need to use DeveloperForce.Force as the namespace and the name in the NuGet package. Other ideas?

• Salesforce.Force: concerned that it's not only not officially supported by Salesforce but "Force.com" is technically no longer a thing.

• Salesforce.Lightning: meh, doesn't feel right to me.

• WadeWegner.X: not sure I want to have my name in the namespace.

Any other thoughts?

I also worry about the impact in NuGet and elsewhere. I'm not sure if there's a method to redirect a package. (I guess I could update it to take a dependency on the new one, but it would just break everyone's code.)
