updated version of tomcat to last 6x version (6.0.37)

See
http://apache.mirrors.pair.com/tomcat/tomcat-6/
caching changes so far (tested that caching works, but not yet tried a complete installation from cached version)
- Merge branch 'add-caching-to-master' into add-caching-to-devel,
- resolve conflicts in esg-node from merge
- replace a couple of extra calls to "git clone" with the caching equivalent (fetch_url_with_git)
- modify fetch_url_with_git to permit 2 args (as with fetch_url), in which case the first is the local path
**not tested running it**
