Subject: [PATCH] search prototype

- uses minisearch https://github.com/lucaong/minisearch for client side filtering of event data on the /calendar page
- tweaks mustache generated html so that the "data-event-id" is "caldaily_id" ( was event listing id )
- tweaks the mustache getEventHTML() , moving  "set page title for specific id" to the caller that needed it.
