Replace Gatekeeper

[Swader]

Due to some critical issues that render Gatekeeper completely insufficient for any kind of production use, namely this, this, this, this and more, and due to the complete unresponsiveness by project maintainer, I now consider Gatekeeper vaporware and am looking for alternatives.

Currently, the most likely course of action is grabbing what works from GK, putting it into a new package, and developing the rest of it properly around some interfaces. This breaking away from GK is planned for version 3.0.

Another newly found critical fail of Gatekeeper is the default length of fields in the database. One of the more ridiculous ones is usernames being restricted to 20 characters. I tried to address this here, but I'm just about ready to officially declare Gatekeeper as abandonware. An alternative needs to be found / made ASAP.
