[Tagging] Proposed features/trailblazed=poles; cairns; symbols ... Approved

[Peter Elderson]

   - Tag trailblazed=no may not be used too often. This probably makes
   sense only when there is blazing highly expected, but not exists.


Still fuzzy... Trying to come up with an example:
trailblazed=no indicates that blazing is expected, but doesn't exist. This
could e.g. be the case in snowy areas where the trail is visible on the
ground only in the summer.
