Title: Issue #400 - Added null check to glimpse.hud.js > processContentType function

Updating the HUD with an AJAX request that has not content-type set causes the following error

Uncaught TypeError: Cannot call method 'indexOf' of null

Added a null check to return an empty string if no content-type header is set.
