v2.0.0-beta.12

Fix issue with negative/zero ids in point object layers

• i18n: Update translations
• PointObjectLayer: Don't add empty tiles
• DataMouseListener: Don't highlight or select objects with negative ids
• MapillaryURL: Ensure ids are positive
• Add a remote control endpoint for setting filters on Mapillary imagery
  • http://localhost:8111/mapillaryfilter -> Reset user filters
  • http://localhost:8111/mapillaryfilter?start=2020-01-01T00:00:00Z -> Reset user filters, set start date to 2020-01-01
  • http://localhost:8111/mapillaryfilter?end=2020-01-01T00:00:00Z -> Reset user filters, set end date to 2020-01-01
  • http://localhost:8111/mapillaryfilter?organization=1805883732926354 -> Reset user filters, set organization to show to Kaart

They can be combined (i.e. /mapillaryfilter?start=&end=&organization=<organization).
Start and end dates must be parsable by Instant#parse (see https://docs.oracle.com/javase/8/docs/api/java/time/Instant.html#parse-java.lang.CharSequence- and https://docs.oracle.com/javase/8/docs/api/java/time/format/DateTimeFormatter.html#ISO_INSTANT )

• Remove unused code, unused methods, cleanup warnings
