generator: Properly handle boolean attributes when parsing the XML

Browse Source 
In a lot of places, we were only checking the presence of boolean
attributes, like "array", automatically assuming they were true. This
meant that we didn't allow setting them explicitly to false, which
apparently is needed for some bindings.

For all boolean attributes, we now use the GetAttributeAsBoolean method
added in the previous commit, to correctly check the value of the
attribute. As before, if the attribute is not present, it is considered
to be false.

Thanks to Stephan Sundermann for noticing this issue.
