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.
