By almost entirely eliminating text subsitution, we can avoid the situations where special characters in tags or titles gets the macro confused.
These are quite intricate changes, and so I'd appreciate any help reviewing and testing, many thanks.
Fixes#3427
It's a bit gross that we have to change the filename used to reference the JS file. This is to make it work with the webserver.
At the moment, the webserver exposes system tiddlers as plain text renderings, and ordinary tiddlers as full HTML renderings through a view template. So we have to use a system tiddler title for the JS file.
The workaround I'm thinking of is to remove the blanket exposure of system tiddlers, and instead have a list of system tiddlers that are specifically exposed through a namespace like `127.0.0.1:8080\lib\tiddlywiki.js`. That can't clash with a tiddler title because tiddler titles are URI encoded and so can't contain slashes.
* Explore externalising TiddlyWiki's JS core into a separate file
* Fix missing newline after copyright notice
* Add an error alert if tiddlywiki.js can't be loaded
this reverts #3070 which prevents dragging text from one codemirror instance to another
there are other ways to solve the issue I tried to solve with this, so we should revert this to the standard behavior
* Storyviews expose a static "singleTiddlerMode" property to determine if they require single tiddler mode
* Navigator widget adds a "singleTiddlerMode" attribute; when set to "yes", the story list is entirely replaced during navigation
* Navigator widget now updates "list" field of $:/HistoryList with a more accessible version of the history list
* Add a getstoryviewsingletiddlermode[] operator so that we can obtain the story view STM status for passing to the navigator widget
Makes things a bit easier to follow when working in multiuser environments.
@inmysocks, @danielo515, @arlen22, @pmario, @drakor does this make sense for your use cases?
