Intention of moving to a bundling approach

The idea here is to wrap up like-priority extension scripts into single files.

Based on `Glimpse.Core.Extensibility.ScriptOrder` enum, build a bundle for each section of the document. Rather than rendering out a script tag for each script, a single, bundled file would be injected in their place.

A possible further optimization would be to detect for a count of one and write out the raw script if there only exists one to save on serialization costs.

Open to conversation, suggestions, pointers, gotchas or insights anyone has to offer.
