[master] Plugins import from url

Plugins import from URL
checkbox for update checks (autoimport un update)

a json file on github with direct links to textfiles with base64 strings that can be loaded by bot

it would then work like a catalog of plugins that you can subscribe to and then they get the updates automatically

i know i can put multiple listeners and its flowchart in one plugin but i cant easyly enable/disable them speperatly from each other from UI

      "bot_version": "^0.0.0",
      "link": "https://raw.github.yadayada/plugin2.txt"

catalog file maybe can look like this
and these are imported disabled by default (on update => last state)

import/update for plugins from url would be nice
so its possible to subscribe to a plugin and the maintainer can
roll out updates
