[Building Sakai] crashes on KnowledgeBase tool

Hi Peter,
I took some time to fetch a sakai 2.6.3 and get the KB working. I've ran
into 2 issues:
1) JDK 1.5 does not contain the stax stuff, and there seems to be some
classloading issues. So I used the strategy from the 2.5 version of the KB
tool to deploy stax-api and stax to shared.
2) The spring dependency structure has changed, sakai 2.7 uses the 2.5
spring fragmented jar structure, whereas spring 2.0 used a single jar
containing all.
The 2.6 version is available at:
https://source.sakaiproject.org/contrib/edia/knowledgebase/branches/sakai-2.6.x/
I also updated the installation guide:
https://confluence.sakaiproject.org/display/KBT/Installation+and+Setup+Guide
With kind regards,
