Registers an alternative way to access the cache and set up a custom compiler and loader. Intended for use by
plugins.

A cache alias just adds syntactic sugar for users wanting to manage and access the cache from a plugin namespace.
The registration creates references to `getCachedTemplate`, `clearCachedTemplate`, `clearCache`, and the `custom`
object in the alternative namespace.

You can also register the name of an alias to use on view instances (optional). A property of that name will be
created on each view. It references the declarativeViews property of the view.

@param {Object} namespaceObject              e.g. Backbone.InlineTemplate
@param {string} [instanceCachePropertyName]  the name of the cache property on a view instance, e.g. "inlineTemplate"
