Add item filters

This adds the following filter options that allow for restricting the
set of items that are read from the appointments file:

* --filter-type
* --filter-start-from
* --filter-start-to
* --filter-start-after
* --filter-start-before
* --filter-end-from
* --filter-end-to
* --filter-end-after
* --filter-end-before
