First pass at external image support A bunch of little changes that together enable external image support. Try: ``` tiddlywiki editions/tw5.com --verbose --build externalimages ``` Then open `externalimages.html`, look for the images in the more/types tab of the sidebar, open them and verify that they are set with an external SRC attribute, not a data URI.

Extend support for .ico files Now we can parse image/x-icon tiddlers for display, and provide an entry for them in the type dropdown.
