added schemas/VegBIEN/data_dictionary/schema_docum.pptx from Brian McGill

merged inputs/VegBIEN into schemas/VegBIEN, since for the purposes of the data dictionary URLs, VegBIEN is primarily an exchange schema

removed no longer needed inputs/VegBIEN/fs symlink. use web/.fs instead.

web/.fs: changed to point directly to the svn root, so that the VegBIEN dir does not contain any recursive symlinks

/README.TXT: Mac settings backup: to Dropbox: stop Dropbox beforehand to prevent Dropbox from trying to capture filesystem events while syncing

/README.TXT: Mac settings backup: exclude ~/Library/Thunderbird/Profiles/9oo8rcyn.default/global-messages-db.sqlite because this file does not sync (issue #907)

web/links/index.htm: updated to Firefox bookmarks: oXygen XML editor: added download link for the version (13.2) that works with NCEAS's license. bash: added fix to enable Ctrl+Arrow to work. GVFS: added links for file permissions bug. iPlant: added Atmosphere/Data Store links. Quick links: updated vegpath.org link to `vegpath.org.`.

web/username_prefix.php: username/password prompt message: added instructions to always append "." when visiting the homepage of the site ("vegpath.org.")

schemas/VegBIEN/VegBIEN data dictionary.xlsx: moved to schemas/VegBIEN/data_dictionary/

schemas/VegBIEN/VegBIEN data dictionary.xlsx: updated: analytical_stem_view: approved by/to discuss: renamed to * (removing "approved by") because the participants in today's conference call indicated that they were happy with the definitions, and the issues raised before the call had been addressed
