Fix bug when generating WAR

I fix a bug that occurs when I generate a WAR file in production
environment using "grails prod war".  The calendar.coffee file includes
a locale-specific JavaScript file but this information is not available
at compile time.

Now, I include the locale-specific file via <asset:javascript>.  This
requires that the asset calendar-view.coffee is loaded afterwards.
Thus, I have to remove the dependencies from calendar-view.coffee.
