Dynamic loading/unloading of plugins (#4259)
* 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.
