Add visit outcome details

[GiovanniMancini]

This PR proposes to add a screen to insert a detailed visit outcome. The Agent can choose

• a visit date (but not a time)
• products she discussed with doctor and left a sample
• products she discussed with doctor and left a depliant
• text note which is showed as visit headline in doctor screen

Visit is saved in Visit collection. Products discussed are saved in a separate db collection to preserve data normalization.
