Untie logic for SCRIPT_NAME and PATH_INFO
SCRIPT_NAME is used as fallback for virtual-root when virtual-root is unspecified in cgitrc and PATH_INFO is used as fallback for the query- string parameter 'url' when the latter is unspecified. But until now, the use of PATH_INFO depended on virtual-root also being unspecified, i.e. it was impossible to use PATH_INFO when virtual-root was specified. This commit makes the fallback on SCRIPT_NAME and PATH_INFO independent code paths, i.e. it is now possible to specify virtual-root in cgitrc while still using PATH_INFO (instead of rewrite rules) to get 'pretty urls'.
