/: re-set svn:ignore on new root (/trunk/)

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).

added standard svn dirs branches, tags, trunk

web/links/index.htm: updated to Firefox bookmarks. added links to the sPlot ERD. Dropbox: added information about a missing upgrade notification when you use the Dropbox client to look up a file on the Dropbox website.

/README.TXT: added note that shell scripts should always be read-only, so that editing them while an import is in progress will not crash the import (see http://vegpath.org/links/#**%20modifying%20a%20running%20shell%20script)

/: svn:ignore the new extern/ dir, which will contain non-UCSB files

bugfix: inputs/.TNRS/schema.sql: scrubbed_family: Name_matched_accepted_family was missing from the TNRS results at one point, so we are now using Family_matched as a workaround to populate this. the workaround is for accepted names only, as no opinion names do not have an Accepted_name_family to prepend to the scrubbed name to parse.

inputs/.TNRS/schema.sql: reexported from live DB, which changes the element order

schemas/vegbien.sql: plot.**, analytical_stem_view, analytical_plot: added project_contributors

schemas/vegbien.sql: added project_contributors()
