[Upp-changelog] Fixes and improvements in XML parser

[Tomas R. <ry...@vo...>]

Hello everyone!

I've just posted a few changes I made to the XML parser. I added support for 
the xml:space=preserve attribute and made a few local optimizations to 
improve XML parsing time (in one of my commercial applications, I thus 
managed to decrease xml load time by about 25%, but this includes additional 
parsing on top of pure xml, so I hope the figures for the XML parser as such 
might be even better).

Regards

Tomas
