Script to fix old amazon dyna references
Do the popups 10px away from the mouse pointer to avoid flicker
Add random_line dyna snip (from @lazyatom)
Allow more options for link_to

We allow for a title attribute to be specified.  Also added a link_to_fragment dyna that takes a fragment identifier to allow uarls with #fragments in them.  Added this separately as adding more optional args to link_to was becoming unworkable.
Add script to find and fix {vanilla-display-url} links

Currently only the simple ones though, some we have to fix manually, some we have to fix differently.
Give the vanilla-r renderer uses it's own default layout

This means we can remove all the vanilla.r-ish things from the default template as they won't be present for content that doesn't have the vanilla.r metadata to power it.  age, hierarchy, author, back-links, etc.
Update page_title to cope with a missing snip
Smarter link_text in link_to

If there is no link_text provided then use the title or name of the snip if it is a real snip, only then fall back to the default text provided by the link_to call itself.
Script to convert the rebol string for metadata into a yaml hash

We process it a bit so that there are strings, numbers, arrays, hashes and dates.  We also remove any extraneous "name" metadata and replace with "title" attributes, if it's different from the snip name.
Some scripts that find references that need fixing

These need to be manually fixed, and it's not clear what in some cases to do.  For dyna we need to re-write them or decide that it's not something we want to support.  For case-dependent link_to refs we just downcase the ref or remove it if it's not something we actually have a snip for anymore.
