BUG: Data returned for schedules and programs is not valid json

[cwchapma]

Most json parsers cannot parse multiple root objects. Would have to parse each line separately. Changing it to an array would fix that.

Data returned for schedules is currently:

{"stationID":"10130","programs":[...]}
{"stationID":"10131","programs":[...]}

Should probably be:

[
{"stationID":"10130","programs":[...]},
{"stationID":"10131","programs":[...]}
]

Same for programs.

The current method returns each JSON object as its own entity. In the PHP grabber scripts, we pull in each result as a line, then decode the JSON on a line-by-line basis. This means that each schedule can be parsed individually, cutting down on the amount of memory required at the client.

Initial tests also showed that PHP wasn't very efficient in creating very large arrays (hundreds of thousands of elements) and then turning it into JSON. By creating each stationID as its own entity we can pre-generate and pull the JSON directly from the database instead of trying to calculate on-the-fly when the client makes its request.
