Now builds page using kotlinx. Added support for static web content.
Removed code to re-direct to static web content if it exists.
Minor changes to comments. The recursive API crawler now uses a data class instead of a mutable map.
DemoBench: Misc usability improvements:
- Pre-fill details for some fictional banks when Add Node is pushed.
- Make services a checkbox list rather than one where you have to know how to use the keyboard to do multi-select.
- Make web server launch button spin until server is launched to show activity.
- Suppress an exception that spams the log due to inability to load all the states. It'll get fixed as part of the vault API and serialisation work.
