Scalable Dynamic dashboard widgets

[hugobarragon]

At the moment its impossible to use this dashboard dynamicly.
Where can exist widgets that are not included in the wiedgetList...
Should have a error prevent check here:
Check here: https://github.com/Raathigesh/dazzle/blob/master/lib/components/Widgets.js

and maybe even replace the widget with a Not Found for the user to delete intead of a dashboard crash.
It is not relieable to get a widget from the current layout and expect it to be in the widgets list.
I cant contribute no problem

My current Idea:
If layout widget does not exist on the widget list:
Present a not found widget that instead of complete crash(here the user can now remove thsi widget from his dashboard),
this not found widget can be either get from prop from the developer or we have a default
