Gajim omits boolean field when it's false
Gajim doesn't send boolean field when submitting adhoc command form if the value is false. In XEP-0004, there's no mention that if there's no field element provided for particular var, it should be set to false by processing entity (lot of entities just don't set it to false, because they think the value should be unchanged).
There's only mention that <value/> should be processed as "false" by processing entity (http://xmpp.org/extensions/xep-0004.html#protocol-fieldtypes).
Is there any reason why Gajim omits those boolean fields and leaves it on interpretation of processing entity?
