RFC: Allow plugins to be declared/loaded as a React component

[joaquimrocha]

We have discussed a few times that we need to create a more structured life-cycle for plugins, namely plugins should be able to understand when they're being loaded, and when they are being disabled, unloaded, etc.

I think @illume has previously suggested that we could have plugins be just a react component, since components already have a life cycle they can control.

This would also make it easier for plugins to set up hooks that don't necessarily need to be run in a visual component.

Any comments about this?
