I used the `simple_tag` decorator and found out literal Boolean arguments are parsed as empty strings.  Numbers are okay and context variables too.

Here's my reference: https://docs.djangoproject.com/en/1.4/howto/custom-template-tags/#simple-tags

I will try to modify the `static_with_build` and `static` signatures so they will accept a Boolean.  I am leaning to use context variables of `True` and `False` with their appropriate boolean values like suggested here: http://stackoverflow.com/questions/4557114/django-custom-template-tag-which-accepts-a-boolean-parameter - it's more explicit than having to use `1` or `0`. :)
