Revamping the DashboardCalendarSelectModal

[cbnt7437]

• Button to add assignments directly from DCSM (thanks Calynn!)
• Work blocks for To-Do (thanks Frank!)
• Toggle option for order- show by due date, class, time needed, etc. (thanks Tobias!)

I've got the "toggle option for order" task

For tabs: https://bulma.io/documentation/components/tabs/

      <div
        v-for="c in courses"
        :key="c.crn"
        class="panel-block"
      >
        {{ c.title }}
      </div>

@Apexal Does it make a difference if I use Buefy tabs instead of Bulma tabs? The Buefy ones seem a little easier to work with (plus the modal seems to be a Buefy modal).

Frank and I decided that, at least for now, we are gong to separate everything in tabs based on whether it's an assignment, course block, or todo (rather than sorting by due date, course name, etc which is a little harder to do).
