Inconsistent behavior with boolean values

[uzikilon]

I am not sure if its a bug or a feature, but I would expect booleans to be converted to the string value of them (e.g. bool.toString() which will result in 'true' or 'false')
This is the current behavior with handlebars 1.3.0:

var tmpl = Handlebars.compile({{bool}});
tmpl({bool: true}); // 'true'
tmpl({bool: false}); // ''

Same issue as #827. Closing to track there.
