Highlight the status of extensions and contexts.

Hello,

Some time ago I sent a suggestion for improvement (https://github.com/kdzwinel/Context/issues/10) and believe that you can not implement it.

I love the extension and want to help improve it. I then decided to develop the implementation and suggest you to integrate your extension.

Any questions I am available.

Big hug,

Thiago

EDIT:
Hello again!

I took that was hands-on and also implemented another feature that I had suggested earlier.

When a new extension is installed, you can now create a new context directly in the notification.
