Update translations

Fix JOSM-19516 (again). Also update translations.

Translations and bug fixes

* Translations have been updated (and should now work properly because
 they have been updated).
* Some bugs have been worked around during download (introduced as part
  of the Download Manager window)

Enable point object features

* Add Download Panel (Kishan)
* Various GUI interactions have been fixed (Kishan, Taylor)
* Filter for panoramic images (Kishan)
* Serbian (Latin character) translation (not currently working -- needs
  point release)
* Various fixes/modifications for uploading images (Kishan)
* Fix JOSM-19516 (scaling on HiDPI w/ MS Windows) (Taylor)
* New advanced config option ("mapillary.download.timeout") to increase
  time before timeout when downloading images. Defaults to 30 seconds.
  (Taylor)
* Toggle dialogs should all have the ability to have shortcuts (Kishan)
* Fix issue where downloaded image area wouldn't be shown (Kishan)

Performance enhancements

* Don't draw image sprites when zoomed out (low zoom)
* Use sprites for Mapillary images
* Update JCS to JCS3 (package rename, see JOSM-19208)
* Fix a crasher when Mapillary servers have issues

Images no longer flicker between images

* Also, there is a new option to disable the JavaFX date pickers (they
  cause issues on some machines)
* Next/Previous/Red/Blue image actions can now have defined shortcuts
* JavaFX issues will no longer kill the plugin

UI improvements, some bug fixes, and removal of deprecated functionality

What is new:
    * Date Pickers now have a GUI (requires JavaFX, which means Java 11+ or a version of Java 8 that has JavaFX, which means either a Linux distribution with OpenJFX or Oracle Java — I know that JOSM wants to move to Java 11, which they are likely to do as soon as Java 8 is EOL, which is supposed to occur at the end of the year).
    * Group filters (if the user is part of a group)
    * Images are now semi-transparent if another sequence is selected
    * The Mapillary Layer goes below the data layers, to make it easier to see OSM data features
    * Several enhancements for viewing 360 imagery (painting while panning)
    * Better detection for Mapillary source tag in changesets
    * Built-in mapcss file and images for point detection (effectively disabled right now)
    * UI button to disable sign detections in images (so you can see what was actually detected as a sign)
    * Sign detections work again (they had been broken for awhile)
    * Several crash fixes
    * Some code was removed since JOSM has the same functionality (MapillaryUtils.browse() specifically)
    * Organizations with private imagery can see the private imagery if they are logged in, and the appropriate setting was used at download
    * Fix a deadlock
    * Icon updates
    * Use Mapillary's mapillary_sprite_source icons (included via git subtree, see d66d6bc, since GitHub does not export submodules as svn:externals)

What has been disabled:
    * Point features and related features

Release 1.5.11 (for JOSM >= 13643)

Mainly i18n and dependency/tooling updates.
Adaptions to new JOSM API.
New language Italian!

Due to a breaking change in r13643, the minimum JOSM version has to be bumped to a later version than the current `tested` version. So this release is two-part for JOSM versions before and after this change (see a3b27111f3822dfc12cca551be1cc2494bb5af19).
