Modified generated .htaccess File
The auto-generated .htaccess-file now always adds a RewriteBase and defines
a more strict rule for index to be index.php
This solves the problems by 2 web-hosts I've had were RewriteBase was required
even it was set to the root (/) and the default file wasn't index.php => it
worked only when set directly to "domain.tld/index.php" but not to "domain.tld"
