fix: inputs/VegBIEN/Redmine/svn/.htaccess: updated repository URL to point to 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).

inputs/VegBIEN/Redmine/svn/.htaccess: updated to use much faster direct repository URL rather than Redmine web interface, now that the repository itself is publicly accessible in addition to the Redmine view of it

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).

web/**/.htaccess: Use InheritBefore RewriteOption so that the outermost dir's rules are always run first. This is necessary so that all the HTTP_HOST and dotpath handlers, etc. are applied before any fallback handlers, without needing to copy and paste each rule into every .htaccess file. (Note that the InheritBefore RewriteOption is only available in Apache 2.4.) The outermost .htaccess file, however, must not use InheritBefore because this would inherit rules from the global Apache config, which normally should not be run and which cause an infinite redirect loop.
