Upgrade to TiddlyWiki 5.1.21
This release upgrades to TiddlyWiki 5.1.21. The bundle is copied directly from TiddlyWiki5-production, so it will have the same file structure for your version.
I've also added /assets/tiddlywiki/
to serve the tiddlywiki folder. It will server whatever folder is being used, so if _datafoldertarget is set, it will serve that folder. You can use this URL instead of the CDN URL described in TiddlyWiki5-production, since it is copied directly from that repo.
This is a more advanced solution than using $:/core/save/all-external-js
. If you have many wikis in your TiddlyServer installation, they can all use the same files which will get cached in the browser and shared between folders.
