[Improvement] Add Weight and Blood Pressure events

[idalioreis]

Hi I think it would be important to condense all the information in just one place that is usually needed in a doctor's appointment. In diabetes, weight and blood pressure are important data to record for monitoring possible diseases. These fields could be added to events.

Thanks
