- added color customization in render-config.xml
- added ability to scale size of Venice logo in footer
- added ability to customize size of site logo, as well as add a hyperlink

instead of in JRE extensions directory (only Java extensions should go in
JRE extensions directory)
- close to requiring JAXP 1.1 (will still work with 1.0 though)
