Unable to select similar locations in Event Location tab

The Supplemental Address 1 and Supplemental Address 2 lines are not recognized as differentiating different event locations, it appears. An example of when this is a problem is when rooms at a hotel for recurring monthly brunches are put on one of those lines. Updating the location is inappropriate since different months end up in different rooms. Creating an additional location apparently succeeds, but one is unable to select between the two (or more) locations with the same address, as only one appears in the Use Location dropdown. Looking in civicrm_loc_block shows they are all there. So my guess is that the widget for the select that only includes Street, City and Province is ignoring the other locations.

Recommended fix: Add Supplemental Address 1 and Supplemental Address 2 as additional fields on the right of the existing fields, if they are non-blank, in the select widget.

If approved, JMA will submit a PR to master branch for this.
