Delete multiple symptoms at once (command 5)

[jared-ee]

Currently, only one symptom can be deleted at once with command 5. Experienced users might find it cumbersome if they want to delete a large number of symptoms but not all of them. To resolve this, command 5 should accept multiple inputs in a string (similar to how it is done for reporting symptoms, command 1)

>>5

1. symptom1
2. symptom2
3. symptom3

>>12

Successfully deleted symptoms! Here is the updated list of symptoms:
