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).
schemas/VegCore/VegCore.ERD.mwb legend images: resized to medium-sized squares because apparently MySQL Workbench can't handle rectangular or very large images (it distorts them or resets them to their original size when the diagram is reloaded)
Added lib/MySQL_Workbench/connector.png, solid_line.png, dotted_line.png
