181 override xrm namespace

[misoeli]

Allow for overriding the Xrm namespace, providing a custom one if needed.

Instead of wrapping Xrm in another namespace level (which would require an additional namespace declaration in both xrm.d.ts AND all version-specific files, simply renaming the namespace keeps the needed changes down.

Still not sure it works. It looked as if VS was acting up post generation, but I would prefer a re-review.

Fixes #181 .

@skovlund Looks OK to me after retesting. Most likely just a case of old dependencies. Would like you to have a look though.

pulling and attempting to compile (although I'm not an F# dev). Thanks SO MUCH for this -- we were a bit stuck on our attempt to bring TDD into a project with XrmDT!

[majblackburn]

This has resolved our issues with the conflict between @types/xrm and XrmDT. I'd like to suggest "XrmDT" instead of "xrmns" as a default, but I'm in no way complaining! Thanks again!

@misoeli I've looked through the changes and it looks fine. However, I've not tested and therefore have not verified that we have caught every instance of "Xrm".

@majblackburn I'm not entirely sure I understand your suggestion. The namespace still defaults to "Xrm" (for backward compatibility) and not to either "XrmDT" nor "xrmns" (by the way, we usually abbreviate the tool "XDT"). However, "XRMNS" is used internally in code as placeholder text before replacing it with the custom namespace name. If you are referring to the argument "xrmNamespace" given the alternative command "xrmNs" I think this might be better abbreviated to simply "ns".
