web/people/Brad_Boyle/data_provenance: abbreviated to provenance to enable shorter URLs

added web/people/Brad_Boyle/identifiers

added web/people/Brad_Boyle/identifier_examples, which is used by the VegBIEN data dictionary

web/people/Brad_Boyle/*/.htaccess: set the destination filename using RewriteRule env, to allow escaping " " with "\ " instead of the difficult-to-read "\%20"

web/people/Brad_Boyle/*/.htaccess: use relative paths to new symlinks to avoid hardcoding paths

web/people/Brad_Boyle/: added symlinks to Brad's files that are used in the data dictionaries

schemas/VegBIEN/attribution/: moved into schemas/VegBIEN/planning/

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: web/people/Brad_Boyle/.htaccess: only forward requests for a term defined by Brad to the attribution/ subdir, so that Brad.vegpath.org shows a directory listing instead of forwarding right to the attribution doc

bugfix: web/people/Brad_Boyle/.htaccess: set %{ENV:innermost_dir} to Brad_Boyle
