Multiple valid destinations for a single journey

New feature

The destination field now lets you enter multiple stop IDs or stop names (feature request by @CoatsyJnr).

When multiple destinations are provided, journeys to all of the destinations are calculated and whichever one has the earliest arrival time is the one that's shown. So for example if you specify 'Gordon to Central Station or Gadigal Station' sometimes you'll see the Gadigal journey details and sometimes you'll see the Central journey details, entirely based on arrival time.

Changes since last release

• Fix a minor issue where selecting 'all valid sensors' didn't include 'destination detail'
• Fixed a previous missing config entry property issue when upgrading to previous beta releases
