Add support for additional url parameters

[kellyhutchins]

The 4.x Layer methods fromArcGISServerUrl and fromPortalItem make it easier to support adding a layer via url or portal item id. I think we should add support for these to the app base urlUtils in order to support some of the additional online url params listed here:

@driskull what do you think?

That sounds like a good idea. Lets just make it so if its not in the URL we don't load the modules that use it.

yeah that's easy... ok I'll make the update.
