Add new directory structure. Tags will contain current and past releases, and stable will contain any bug fixes to the current stable release so users won't have to get the potentially broken trunk build to fix a screwup in stable.
Trunk updated to 0.9 git-svn-id: http://kusabax.cultnet.net/svn/repo/stable@176 73d99b7e-4f53-4972-b7b7-2ecd3c4d89ee
