Subject: Create Ender Portal with Eyes of Ender (#4126)

The algorithm was designed so All portals must be facing the center, no matter which block had the eye inserted in last.

Note: Still need to create a block entity so that portals don't become invisible when you relog.

Addresses part of #3445
Fixes #3695
