Day navigator widget: setDates()

  • change logic of setting mCurDate: if it's outside the conference range, set it to mStartDate (and not to mEndDate when it's "greater") -- when going to an earlier conference, starting on the last day doesn't really make sense
  • update() the widget after changing dates. this might be a bit expensive but it ensure that the displayed date is what we want, and since there are many day navigator widgets there's probably no single other place

Hopefully closes #36.

  • Property mode set to 100644
