Title: Add case insensitivity for document attributes. fixes #106

Fix for case insensitivity. Btw I think behaviour of attributes is inconsistent between document and block attributes. Block attributes are in fact case sensitive.

Is this a feature of asciidoc or do you want me to rise bug for it?
