gstlal_inspiral_summary_page: add horizon distance plots back to summary page...

gstlal_inspiral_summary_page: add horizon distance plots back to summary page but plot them on a image pagination component so that they will not be fetched all at once and slows down the page.

Note: this depends on gstlal-visualisation/ligo-scald!36.
