Removed the pmpro_cron_trial_ending_warnings daily cron so trial ending emails will no longer go out. The function pmpro_cron_trial_ending_warnings() is still there if you want to call it yourself. There were issues on some sites where these emails were going out erroneously and also many ways of doing "custom trials" including setting the subscription start date back a certain number of days was not picked up as a trial by this script anyway.
