Add delete functionality.

[JeremyLikness]

Is your feature request related to a problem? Please describe.
I need to be able to delete documents!

Describe the solution you'd like
Provide delete capabilities on the main list page and from the view page. The delete should:

switch to a fake alias (i.e. 'system') and call CheckAuthorChangedAsync to remove it from the existing alias. Then it should call HandleTagsAsync with author changed set to false to do the same with tags. Finally, call the delete method on the context.

Describe alternatives you've considered

I want to do the work can you assign it to me ?

[JeremyLikness]

Hey @JeremyLikness I keep getting exceptions when I try to add items or do searches. I am also not sure where to add the delete functionality, do you mean with "main list"the Home tab page and with "View Page" the view tab ?

That error usually happens when you don't paste the full key. It should have == at the end. I think being able to delete from both home grid and view is ideal.

Ping @Mr-Billionaire did the above resolve your issue?

@JeremyLikness

I using the local azure cosmos DB and it is working now. I guess I also used the wrong AccessKey in the appsettings.json I used the Primary Connection String instead of the Primary Key.
But well now its working and I can start :D
