More dashboard features

The initial release of the dashboard displayed the active ferment graphs for temperature and gravity readings.

The next release has two new sections:

• the 20 latest ferment readings across all active ferments,
• upcoming boil sessions.

The readings section includes the ferment name, reading type, and reading value.

The upcoming boil sessions sections includes name, date, and style. If you have attached a beer.xml file to the boil session, it will also list the ingredients required. You can then make sure you have the required ingredients.
