progress:

- update holdaction to work with updated melcatcher function
- create var for debugging throughout the app (as I touch things
  I'm going to start adding if (debuglog) console.log(data) to the
  getjson requests, so I can turn on debugging of json responses
  globally just by editing a variable (or uncommenting).
- modify error action in the global ajax setup
