moved everything into /trunk/ to create the standard svn layout, for use with tools that require this (eg. git-svn). IMPORTANT: do NOT do an `svn up`. instead, re-use your working copy's existing files with `svn switch` (http://svnbook.red-bean.com/en/1.6/svn.ref.svn.c.switch.html).

bugfix: lib/sh/web.sh: curl(): use --fail so that curl returns a nonzero exit status on error (e.g. file not found) instead of appearing to exit successfully but outputting an error HTML document instead of the file

added lib/sh/web.sh with curl wrapper
