feat(karma): task proposal

Here comes the **karma/test**  task

:warning: the `bower_components` are required so I removed `.bowerrc`

@mgcrea don't you have a component without dep other that angular for the tests ?
I've added a rename option (defaults to true/enabled) to the [template transform](https://github.com/douglasduteil/angular-utility-belt/blob/master/ng-factory/transforms/template.js#L20), so rename should be optional here.
