Major xwiki.com performance improvements

Hi, I'm glad to announce that xwiki.com has been upgraded with the latest SVN version which includes major performance enhancements and is also now setup as a Tomcat cluster. The wikis that were transfered to the "pro" Java Virtual Machine are not running in a cluster but their performance should be really good since the load is limited. The other wikis are running in cluster mode which should allow higher availability with an automated JVM restart and load balancing over two servers. The performance enhancements are especially geared towards the versioning system which was costing a lot of CPU especially due to spamming which is creating hundreds of versions in XWiki documents all over the wiki farm. Now with the recent changes, reading and writing documents with hundreds of version should be much more efficient. Some areas still need improvements like saving a documents with a high number of objets or listing all versions of a documents with a high number of version (the default history page has been limited to 10 versions in order to reduce the load on the wiki farm).
