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).

*{.sh,run}: use simpler .rel() instead of `. "$(dirname "${BASH_SOURCE<sup>0</sup>}")"/...` for relative includes

*{.sh,run}: removed extra space between function name and (), which is apparently not needed even though `help function` includes it. this greatly improves readability, including when function names are pasted into commit messages!

moved lib/*.sh to sh/ subdir so it's easier to find the .sh files among all the other lib/ files

added schemas/VegCore/VegCore.pg.sql.run with install () command (also part of all ())
