First pass at external image support

Browse Source 
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.
