Provide JSON-API for search about maps

[v1r0x]

There was an API, but didn't work for me anymore, so I removed it in #111 .
But bring it back could definitaly something for the 0.2 milestone. Currently we focus on the basic functionality, which IMO doesn't include such "advanced" stuff. Hope you can wait a bit for a solution.

No problem. I'd be interessted in developing an android client if the app is stable. (Does not make sense yet). I'll keep an eye on this project :) Happy coding

Maybe we can gather suggestions about what the API should offer.
@stefan-niedermann what should the API provide in your opinion?

[stefan-niedermann]

Sure, this should be read as "WiP", just brainstorming.

Request

GET /search?q=<string>

Response

ownCloud Maps should search all reachable information in the ownCloud (especially from ownCloud Contacts, but maybe from ownCloud Calendar - Meetings in the near future?). And it should search osm via nominatim to get PoIs.
Mimetype: application/json

{
  /* Contacts from contacts app */
  contacts : [
