Customizable XML coding style for harvested documents

[michmech]

Xonomy's harvesting behaviour currently:

• Xonomy always adds xml:space='preserve' to elements that have text nodes,
• Xonomy always uses the single quote character ' to enclose attribute values,
• Xonomy always encodes quotes and angle brackets as named entities (' etc.), even when this is, strictly speaking, unnecessary.

All these defaults are happening in the functions Xonomy.js2xml and Xonomy.xmlEscape.

None of these things are bugs and they should pose no problem for parsing the XML that has been harvested. However, it would be nice to give users some control over this behaviour.

On the contrary, I think that Xonomy should not be adding additional content of any description. See #40 (comment)
