Fix the things

Kind of needed to get this one out quick

Clients

• Fixed major bug when adding new clients without status
  • status 1 (okay) is set as default for all new clients
  • database additions are required for upgrade
• Fixed bugs with birth date manipulation and displaying
  • If no birth date is present, a nice null is displayed instead of breaking the app
  • Age is always calculated rather than stored in the database
  • Age is not directly editable, it changes by way of birth date being updated

Case Notes

• Updated case notes so that they can be created and edited
• Visual improvements

Other

• Actually remembered to update the version badge
