Implement cache lists

[following5]

OCDE has added the object type "cache lists" half a year ago. A cache list has the following properties:

• internal ID and uuid
• user who created the list
• date of creation and last modification
• type: private, public, public + show in cache listings
• private lists can have a password which allows other users to request them
• HTML description
• list of cache codes (planned: an optional plaintext comment for each cache code)

Cache lists can be marked like caches. If a private password-protected list is marked by another user, the pw is stored with the mark and the list will then be accesible without pw, as long as it does not change.

A feature may be added to create shared cache lists, i.e. lists owned by several users.

It would be nice to add this to OKAPI, which means - if fully implemented -

• a new field cachelists for the geocache(s) methods which returns the lists associated with the cache and visible to the user (or only public/visible lists for auth level 1)
• a method to retrieve accessible cache lists by uuids
• methods to mark or unmark an accessible cache list, which as a password option for marking
• a method to retrieve a list of available cache lists, with combinable options like 'public', 'private', 'marked'
• methods to create, modify and delete lists; most important to add and remove cache codes from/to lists

Details have to be worked out, prio is currently low.

Tell me when (if?) you start. :)

Also, I think it would be worth to design the interface of the methods before you start. There is a possibility that we could prepare a common interface for OCDE's "cache lists" and OCPL's "powertrails".

@kojoty, @wloczynutka (powertrail developers) - you might be interested in following this issue.

It should be not difficult to withdraw API data from PL powertrail module. If anybody of okapi develper is interested in obtain such data, please contact me. I'm able to give a hand with improving power trail module to response witch clear API data (Array or even objects).

If anybody of okapi develper is interested in obtain such data, please contact me.

@following5 will NOT be doing that in this thread, but I have added you because I would like us to attempt to design the "cache lists" API interface in such a way, as to make it compatible with the powertrails in the future. E.g. once external apps start using "cache lists", we should be able to expose "powertrails" as one of the "cache list" types.

In order to prevent necessity of backward-incompatible changes in the future, we would need to design "in advance". E.g. return lists of users (or user_ids) instead of just a single cache list author, etc.

Quite important typo in the previous message (missing NOT), fixed it.
