Docs cleanups
Docs cleanup: Remove unnecessary section in settings

This will improve a little the readability.
Docs: Move some stuff from README to docs
README: Alter note styling so GitHub can render it in a readable way
README: Rewrite and reduce the text to improve readability

The README should be short. We already have the docs for more extensive
explanations.
Cleanup and fix the template
Rearrange views code

Will ease further cleanups.
Add FIXME
Avoid having a view that choses which code to call
Remove other view that choses which code to call

There is a remaining view, but still not sure how to drop it.
Add setting to control if the web UI is enabled or not
