Add "mark as cured" checkbox in new medical history

[aeswibon]

• Additional Feature (may be separated out as a separate issue)
  While viewing saved medical history, For every saved date, ICD and description, there needs to be an option on the right-hand side to "mark as cured". This will allow the system to not only list all the diseases the patient has but also understand which of them is already cured.
