Free trial now 30 days instead of 7

Over the years we’ve heard from some users that our 7-day trial was not long enough to really test out Pushover. Sometimes users would install the app, signup, and then forget about it, only to return to it days later and find that their trial was about to expire. Or users integrating Pushover with a custom IoT project would need a few more days to get their software properly setup to send out notifications.
