Fix #365

As described in #311

Merge branch 'fix-module-export' of https://github.com/EtixLabs/angularjs-slider into EtixLabs-fix-module-export

When the module is imported using AMD/CommonJS, it is expected to expose its name instead of the
Angular module object. This is because angular.module() expects the dependencies as string instead
of actual module objects.

Fix #326. Breaking change: code that relies on the module object to be exported (accessing the name
via `.name` for example) will break, since the name is now directly returned.

In 3afcce95 commit, I changed the behavior of the combined label for range slider. However, this
broke previous implementation, so this commit add an option to configure this feature. The default
behavior is back as previously: If the slider values are the same, the combined label is 'X - X'
