web/**/.htaccess: internal redirects: Use ?&$0 instead of just ?$0 to prevent the query string from being reinterpreted as a dotpath by the destination dir

web/VegBIEN/Redmine/*/.htaccess: Use relative URL paths. This requires adding a RewriteBase directive because these dirs can be reached by symlinks.

inputs/SALVIAS/.htaccess: Removed test RedirectMatch directive

web/**/.htaccess: RewriteOptions: Redirect dir paths without the trailing / to the datasource's homepage, and let dir paths with the trailing / point to the directory index. This is the opposite of the way it was before, and is more intuitive because the trailing / indicates a directory listing, while the trailing / would generally be omitted when linking to the datasource itself.

web/**/.htaccess: handle DirectoryIndex subrequests, which append "index" to the dir

web/**/.htaccess: RewriteOptions: Removed inherit because if the destination is not found in the current dir, a 404 should be returned instead of trying to invoke the parent dir's fallback handler (which applies only to paths in the parent dir). Ideally, we would use InheritBefore to get the subdomain preprocessing, etc., but the parent dir's fallback handler would still need to be turned off somehow when the rule was being run by a subdir.

web/.htaccess: Only forward specific terms (subpaths) to VegCore, not also the dir index itself

web/**/.htaccess: RewriteOptions: Added AllowNoSlash (available in Apache 2.4) so dir paths without the trailing / can be parsed by mod_rewrite

web/.htaccess: Turned off DirectorySlash so that the dir without the trailing / can have a separate meaning (e.g. as the home page of a datasource, rather than a listing of the short URLs available for it)

web/main.conf: <Directory .>: Added `Require all granted`, which is needed by Apache 2.4 to prevent 403 Forbidden errors. This change breaks compatibility with older versions of Apache, but is unfortunately required by 2.4.
