Title: Added helper path callback option 

Example: The following callback allows for automatic loading of helper modules written in CoffeeScript (compiled on-the-fly via the require-cs plugin) under a non-standard location:

require({
hbs : {
helperPathCallback: function(name) {return 'cs!/helpers/' + name;}
}
}, ['main']);

The default behavior remains unchanged.
