Merge remote-tracking branch 'upstream/master' into task.js
don't include scoring/app.js in js/task.js

(examiner can't because there's a different js file for each task)
all js/task.coffee to still work
whoops, this symlink wasn't supposed to be checked in
don't include symlink created by scoring
task Makefiles should not delete themselves
use uglifyjs to make js/task.js unless TABCAT_DEBUG=1
Merge pull request #157 from davidmarin/task.js

Automatically pack task code into `js/task.js` (fixes #143)
