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).
error_stats: Fixed to work on Mac
error_stats: Simplified to use uniq --count option
Renamed get_errors to error_stats and added counts of each error message
Added get_errors to select just the error messages from `map` output
