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

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

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.")

web/username_prefix.php: deletion comments: require ... strikethrough on both () to avoid ambiguity when the deleted part starts or ends with -

web/username_prefix.php: deletion comments: also support strikethrough syntax for clarity: (c_)x@url -> c_x@url

web/username_prefix.php: insertion comments: documented that the semantic meaning of the [] portion also applies, even though it's not included in the linked term name

web/username_prefix.php: added support for deletion comments of the form (c_)x(_d)@url -> c_x_d@url . deletion indicates that the semantic meaning of the () portion does not apply, even though it's included in the linked term name.

web/username_prefix.php: comments: use [] instead of () because in writing, [] denotes insertion, while () (as an editing mark) denotes something to remove

bugfix: web/index.php: fixed bug where full directory index would not display correctly if invoked as /index.php instead of / (caused by incorrect URL)
