*{.sh,run}: runscript targets: use begin_target instead of echo_func so the target name is properly echoed. note that this requires using with_rm so that $rm is properly progagated to applicable invoked targets. (previously, $rm was progagated to all invoked targets. note that with_rm only works inside a runscript target that starts with begin_target.)
moved everything into /trunk/ to create the standard svn layout, for use with tools that require this (eg. git-svn). IMPORTANT: do NOT do an `svn up`. instead, re-use your working copy's existing files with `svn switch` (http://svnbook.red-bean.com/en/1.6/svn.ref.svn.c.switch.html).
*{.sh,run}: use simpler .rel() instead of `. "$(dirname "${BASH_SOURCE0}")"/...` 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 ())
