Include Village-Camp relationship in CAMP API resultset

Is your feature request related to a problem? Please describe. The BMORG is urging (requiring?) camps in a village to also submit questionaires, presumably due to their increasing popularity with both camps, villages, and the placers. Using the camp dataset, there currently is no standard way of identifying the relationship between camps and villages.. Sometimes this data is included in the camp and village description, but that doesn't help any software attempting to identify this relationship. This relation is important because it would allow the presentation of village data, coalesced from the member camps' data, even when the data (such as events) have a' host UID of a camp.

*Describe the solution you'd like** Provide a means to identify the camps which are in a village. Two alternatives come to mind:

In the dataset for a village, include the member camp UIDs.
In the dataset for camps, include the parent village uid if the camp is in a village.

Alternative implementations

Instead of embedding this data in the CAMP dataset, a new API call could provide the data tying villages and camps together.
Instead of embedding this data in the structure currently used for camps/villages, add a second datastructure to the camp API resultset. Currently the response is an (unnamed) array of camps and villages. Instead, the top-level JSON might look like this:
```
{
"camps":   [
                     <existing JSON structure of camp data>
                 ],
"villages": [
                      <JSON structure of village data, including new field for mapping to camps>
                 ]              
}
```
