More style changes to the edit data criteria dialog

- Start and Stop times both have separate date and time fields and they
  fit correctly
- Added updated design for Value and Field Value field
    - Static right now, but format is more or less correct
    - FV is missing the dropdown

Note: Changed spacing between dropdown menu and first input because the
type of inputs change based on the selected value. Needed a separate div
for what changes. Possible to remove spacing, but it wouldn't make a lot
of sense when looking at it with a select instead of text inputs.
Can add more values/field values

- Changing Value/Field Value type now works
- Can add new Value/Field Value by hitting the plus button
- TODO: Make Value/Field Value minimize to gray label when plus button
  is clicked before adding a new form
Values & Field Values are working w/new design

- Value/Field Value forms work. You can add multiple of each and they
  appear in gray boxes with a delete button, which also works.

TODO
- Need to fix some styling bugs that cause the length of the form to
  change
- Need to test with a saved patient
