* Removed all traces of PEAR functions.
* Fixed AirtimeInstall::GetVersionInstalled() to return the correct answer
even when it cant connect to the database. Also fixed return value to
be consistent on failure.
* Fixed phone_home_stat.php and soundcloud-uploader.php
-implemented. Removed ability to specify time ranges for now, and defaulted to looking from now to 24 hours ahead.
Being able to specify time ranges was removed, since we are not using bi-directional communication between pypofetch and Airtime server.
