Better notifications

While trying to do this:

View notifications or popups

I encountered this error:

Too much verbage, should just show the reply.

Some other notes:

Give us some context:

• It'd also be really handy if you could tell us the contents of your version.known file
• What database are you using? (e.g. mongo, mysql, postgres)
• Any warnings or errors in your admin/diagnostics page?
• If this is a programming bug, can you include examples of any Micropub / API calls / webhook pings you make? Otherwise please don't worry about what this means!
• Bonus points - are you able to illustrate the issue with a unit test? If so, submit it as a pull request!
