[aerogear-dev] First go at stats/activity wireframes

[Hylke Bons]

Hey,

Here's an initial version: 
https://raw.githubusercontent.com/hbons/aerogear-design/master/Unified%20Push%20Server/activity-spec.png

I tried to incorporate most wishes expressed in the other thread.

Most notable things:
- Landing page with an overview of stats, most active apps, and error 
messages
- Activity table shows both registration and notification events
- Activity table is per variant, and not all activity on the server. 
Unless there's a usecase to have every event for every app/variant in a 
table I don't think we actually need it. The important thing is to get 
to error messages easily.

Things to do/think about:
- links/entry points to the activity table
- filtering the activity table

This is just the first iteration and we will improve on this.
Let me know what you think.

Thanks,

Hylke
