1. We're maintaining the same code twice which leads inevitably to problems as this one. The createHtaccess routine is only used to use the correct paths to the 404 and 403 document.
2. Updating the ownCloud instance as described in our documentation (`Delete everything from your ownCloud installation directory, except data and config.`) will break the links to the ErrorDocuments anyways and show the default error handlers if ownCloud is not installed in the root directory.

Add JS redirect if that fails (HTTP-based redirects are disabled by
default in more recent Firefox versions).

php_value can only be used with mod_php, using it with FCGI will cause 500 Internal Server errors.  This needs to be set in php.ini manually or set using ini_set().

This reverts commit e1478117.

add caldav and carddav files in their old place for backward compatibility - add rewriterule for caldav and carddav

having a broken web/card/caldav is much better as having no ownCloud at all :)

Made things work on Dreamhost shared hosting
