Notifications: show attached to User, Project and Organization

[humitos]

Render notifications attached to these objects.
This is the first pass of this work and there are some things we need to make decisions and improve.

• Where (what pages) these notifications should render?
• How "global" they should be considered?

Note we are rendering these notifications in the template for now, but in the future they will be rendered using the APIv3: #259

I'm showing all the notifications attached to Project and Organization. However, the endpoint we are creating will only show these notifications to admins/owners. @agjohnson should I do the same here by returning a more specific queryset via the get_context() in the view?

I'd say we should keep all of the notifications in the same location on the page for now, except for the special location in the build detail page. It will be a little more confusing if there are user and project notifications, as these would display at two different points in the page.

I would put the project/organization notifications at the top of the content page, above the project/organization header. I could see us revisiting this later though.
