Add function function url_exists to check, if acces to remote applet is possible.
 * Changes from version 1.0q to 1.0u:

url_exists replaces the old code with fopen. The old code didn't work correctly at wikis with allow_url_fopen off.

allow_url_fopen is set in php.ini. Some internet service providers do not grant access to php.ini.
