Easier adding of trashcans

[InventivetalentDev]

Would be nice to have an easier way of adding new trashcans directly from the app (without requiring OsmAnd).
Things to consider:

• Should users be required to create an OSM account or should it use a single TrashApp account?
• Does OSM allow automated requests (i.e. from a single account behind an API)? Yes they do!
• How can potential spamming of invalid locations be prevented? (especially if the edits go through a single account)
  • Require an account (OSM, Google, etc.)
  • Minimum usage time of the app
  • Ask other users in the same region for confirmation before finally adding
