WIP: Bread app prototype

With the current state it is not possible yet to get an actually working prototype due to the way query gets handled in the resource actions.

Some missing features include:

• Parsing .{number} in name paths

  {
    coordinates: [
      4.840689897537232,
      52.37704828881554
    ]
  } 

• Subscribing to resource updates (or: assigning a user to a resource and then notifying them)
• Preloading in a resource in form
• resource.upsert resource action (or similar)
• (bug) passing query parameters to resource.get and resource.query
