Integrate missing components from OONI Probe desktop app

[hellais]

I am going to use this ticket to take note of all the components that I have implemented in OONI Probe desktop and should be included inside of the design repo:

• Count - Shows a number with under it a Unit (example: 10 Tests)
• Unit - Shows the unit below a number
• HumanFilesize - Displays a filesize in a human meaningful way (example: 10 MB)
• ResultsHeader - Displays a hero-ish header with some stats inside of it
• CardList - Shows a list of cards that are expandable
• ProgressBar - Shows a progress bar for the running of a test

@hellais Do you have screenshots of how you implemented them so I can review/adapt them?

@elioqoshi when they are ready to be reviewed I will integrate them into the design repo and you can review them from: http://openobservatory.github.io/design/
