Tserver scripting, post-commit hooks, dist-upgade, groups and democo.gnumims.com

[Gavin]

• Tserver has been upgraded to Lenny and all that goes with that.
• There are now post-commit hooks on /svnrepos/gnumims and /svnrepos/gnumimswebsite. The www.gnumims.org website is automagically updated on commit and the autobuilder user builds gnuMims.war on commit to that.
• The appropriate system groups are required for the obviously associated actions 'ssh', 'gnumimscommit', 'gnumimswebcommit'.
• Super is used for some scripts in /root/scripto/
  • gnumimsappupdate.sh - update the demo with the autobuilt war.
  • gnumimswebsiteupdate.sh - automatically called by commiting to gnumimswebsite.
  • autobuildrelay.sh - wrapper for gnumimsautobuild, called by commit to /svnrepos/gnumims.
  • gnumimsautobuild.sh - builds the war.

• Common user 'svnuser' has been created for svn+ssh access.
• Apache setup has been massaged for new domain democo.gnumims.com
