Liquid zero does not equal false

[jg-rp]

When used as the left value of the default filter, 0 should not be equal to False. Fixes #62.

Expected behaviour

{{ 0 | default: "something" }}
{{ 0 | default: "something", allow_false: true }}

Output

0
0

Same goes for boolean expressions. Similarly, Liquid 1 should not equal True and 0 is not falsy.

Expected behaviour

{% if 0 == false %}Hello{% else %}Goodbye{% endif %}
{% if 1 == true %}Hello{% else %}Goodbye{% endif %}
{% if 0 %}Hello{% else %}Goodbye{% endif %}

Output

Goodbye
Goodbye
Hello
