Summary	0019900: Add the date when the campaign was created and edited to 'list templates' page
Description	Currently there is no information on when a template was added or modified and sometimes it would be helpful to have that information on each of the templates. Add a column for the date the template was added/created and a column for the date the template was last modified.
