Adds `shadow` and `normal` flags to each entry in `changedTiddlers`,
indicating whether the corresponding version of the tiddler has changed.
Makes the saver handler ignore any changes that aren't flagged `normal`.
Fixes#8902.
Previously, the implicit sort ordering of modules ensured that the "plugins" startup module ran before the "startup" startup module. That no longer holds when experimenting with alternate stores that might use a subtly different collation order (eg $:/core/modules/startup.js vs. $:/core/modules/startup/commands.js), so it's more robust to explicitly specify the dependency
* First pass at dynamic loading/unloading
* Show warning for changes to plugins containing JS modules
* Use $:/config/RegisterPluginType/* for configuring whether a plugin type is automatically registered
Where "registered" means "the constituent shadows are loaded".
* Fix the info plugin
The previous mechanism re-read all plugin info during startup
* Don't prettify JSON in the plugin library
* Indicate in plugin library whether a plugin requires reloading
* Display the highlighted plugin name in the plugin chooser
And if there's no name field fall back to the part of the title after the final slash.
