Minor updates to iCalTV.
The download URLs have changed, so this is a necessary update. Just replace the old
iCalTV.app with this one.
I also took the opportunity to fix a small bug. Previous versions stored some temporary data in
/tmp which caused conflicts if there were multiple iCalTV users on the same computer.
Had left a debug line in 0.6 that caused the scheduled clean-up to produce output, which in turn causes a mail to be sent to the user in the terminal. Now fixed.
