Since I decided to preen mocha and chai, we can no longer generate the
concat file list from the preen config. We must instead explicitly list
the modules we want to concatenate. I placed this config in bower.json
so that most of the time, we won't need to change the Gruntfile.
Also added a concatenation task for test page dependencies.
Also,
* moved fetch out of the list view
* removed unused #last() function
* put test setup lines in their own tiny file.
* added data-cover to view script tags for code coveage reports.
