Quest: Who may access this tower?

[paulklie]

As an alternate solution for #6498, I was thinking of limiting other quests to observation towers with access=yes. However the access tag is currently not that well used on observation towers (only 6.5% usage) so I thought this could help fill this void.

General

Affected tag(s) to be modified/added: access
Question asked: Who may enter this tower?

Checklist

Checklist for quest suggestions (see guidelines):

• 🚧 To be added tag is established and has a useful purpose
• 🤔 Any answer the user can give must have an equivalent tagging (Quest should not reappear to other users when solved by one)
• 🐿️ Easily answerable by any pedestrian from the outside but a survey is necessary
• 💤 Not an overwhelming percentage of quests have the same answer (No spam)
• 🕓 Applies to a reasonable number of map data (Worth the effort)

Ideas for implementation

Element selection:

man_made= tower 
and tower:type=observation 
and disused!=yes 
and not military
and not access

Potentially this could also be extended to defense towers with historic=yes

Proposed UI:
Basically a copy of the "Who is allowed to use this playground? " quest which adds "yes" and "private".
Currents stats:
yes: 670
private: 536
