Micro: Disabling/enabling built-in plugins

[ninedraft]

Would it possible to add command to switch-off built-in plugins such as 'linter' and show plugin state?

Something like

> plugin off plugin_name
> plugin on plugin_name
> plugin list
----------------
The following plugins are currently installed:

autoclose (0.0.0-unknown)  on
ftoptions (0.0.0-unknown)  on
linter (0.0.0-unknown)     off
----------------

It is currently possible to turn off the linter because the plugin provides an option for that. You can run > set linter off. I think a more general solution would be good though so plugins can be disabled even if they don't provide an option.

All plugins now have an associated option to disable them.
