A regression was added in commit 01154e949, which prepends
clutter to the status0 JSON status message.
Example:
```
$ curl 'http://webcam/cm?cmnd=Status0' -u admin:password ; echo
{s}Webcam Frame rate{m}0 FPS{e}{"Status":{"Module":0,"DeviceName":"...
```
The response is not properly formatted JSON and breaks client software.
The problem occurs because a new case statement was added for the
purpose of injecting webcam stats into the JSON status message, but
a break statement is missing and execution falls through to the
following case, which prepends garbage to the output buffer.
With this one-line fix in place, the output is properly formatted:
```
$ curl 'http://tahoe-front-door-cam/cm?cmnd=Status0' -u admin:password ; echo
{"Status":{"Module":0,"DeviceName":"
```
Note that the prior case for FUNC_EVERY_SECOND is also missing a break
statement. That looks wrong to me but it's unrelated to fixing this
issue and I'm inclined to punt that concern to others who are more
familiar with this code.
