Title: Make file extension optional

Files may not always be identified by their filename. I am serving images out of a database, for example, where an image URL might look like:

/assets/4ea013cae9fcaa5e4b010001

By making the file extension optional, we can generate thumbnails with URLs like:

/assets/4ea013cae9fcaa5e4b010001_150x150
