Allow empty constants in templates

The Variable class does not accept empty constants ("") in templates. The error message is:

Could not find variable at start of ""

I traced the error to the __init__ method of FilterExpression. The attached diff fixes the error. I think some of the surrounding if <var> statements should also be rewritten as if <var> is not None, but the diff is restricted to fixing this bug.
