Minimum time to register

Requested by sharky86 in this topic, this is a feature that actually used to be part of phpBB 3 but was removed as of 3.0.1. It adds a minimum time limit (configurable in the ACP 'User Registration Settings' Page) that has to be passed before the submit button on the registration page is enabled.
