browse: Improve origin visits reporting view
This commit improves the view displayed by reaching the
through a wayback machine like interface.
Relevant links to latest full visit, first full visit and last visit
for the origin are first displayed.
The full SWH visits history is then available through three visualization
- a stacked histogram displaying the amount of visits by month (visits are stacked by status) and enabling to filter the visits according to a specific year
- a calendar view giving visit details for each day of a selected year
- a raw visit list for the selected year
Visits can also be filtered the following ways:
- full visits pointing to different snapshots
- all full visits
- all visits
