Front End Refactor

[pythongosssss]

Functionality should basically all be the same with some minor changes and additions

• more modern code, use of modules, async, classes etc
• you can add custom frontend nodes + scripts using a simple js extension api with a few hooks
• dynamic prompting was changed to a built in extension
• reroute node added as a built in extension
• minor change to the ui - the interrupt button was moved next to the currently running prompt when viewing the queue (simplified the code and more consistent with the other items in the list)
• queue and history should auto refresh when socket status updates are sent
• dialog scrolls internally if too much text
