#56 parsedcal-*-files in /tmp are world-readable

[Solo P.]

If the option for saving parsed cals in /tmp is set to 'yes' the file is
saved in /tmp world-readable.

Adding following line to 'functions/ical_parser.php' solved the
problem.

line 1165: chmod ($parsedcal, 0640);

Fixed in CVS. I decided to use mode 0600, however. There's no reason for the web server group to have read access, either.
