web/BIEN3/Redmine/wiki/.htaccess: documented that this dir is needed because Apache does not support dangling symlinks

web/BIEN3/Redmine/wiki/.htaccess: just use this dir as symlink dest, since the dir name is the same as the URL path within Redmine

schemas/VegBIEN/: moved Redmine/, TWiki/ to web/BIEN3/ since they relate to the BIEN3 project as a whole, not just the database

schemas/VegBIEN/: moved Redmine/, TWiki/ to web/BIEN3/ since they relate to the BIEN3 project as a whole, not just the database

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

fix: inputs/VegBIEN/Redmine/wiki/.htaccess: redirect to new main page when accessed without trailing /

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).

web/**/.htaccess: RewriteRules: ensured flags are in alphabetical order

web/**/.htaccess: Use [qsappend] flag with all RewriteRules to ensure that the original query string is never lost

web/**/.htaccess: Removed preprocessing commands that need to run for every dir, because these are now inherited from the outermost .htaccess using InheritBefore. This allows the inner .htaccess files to focus just on the fallback rewrites, without needing lots of boilerplate code (except for the obligatory RewriteEngine/RewriteOptions/SetEnvIf preamble).
