 Bug 2669: Change checkboxes to radio buttons on dictionary

On creating new dictionary for report, the choice between "All dates"
and "Date range" should be a real radio button, not 2 radio buttons with
different names (which means they could be selected altogether...)

Note that I don't understand what means 'All dates', there is no
condition generated for the dictionary. We should not have to select a
field if we don't want to add a condition on it :)

Test plan:
Create a new dictionary for the Patron module, then a date field
(dateenrolled or birthdate, etc.)

Confirm that the radio buttons now behave as radio buttons...

Looks so much nicer too!

Radio buttons display as expected.
