Allow each tracking record to contain arbitrary tags.
Those tags are generated via an API and can be extended by foreign
extensions or for individual projects.
Existing operating_system was moved to this new feature.
The update command allows to migrate existing records to this new
feature.
Those flags can be used when configuring widgets.
A new flag was added bot:yes and bot:no.
Bots are now tracked but flagged.
That new feature allows to build fine grained reports and makes the
extension way more flexible. Possible new implications:
- Show visits from none bots
- Show visits from bots
- Show visits from specific bot
- Add color to page views per page (bar chart)
to color bot or none bot
WIP:
- Update Yaml file to work like before, no bots in widgets
- Add documentation (widgets)
- Add documentation (migration *.yaml)
