Multiple choice for gate positions

[Raphfrk]

Instead of
X=49
allow
X=49,50,51,52

This should work like tier selection in Runecraft

Or maybe just keep it to X=90 and then have the port tied to # 90 portal blocks?

The MC basic code will flood an obsidian frame with # 90 when lit, vanilla. Tying #90 to the server portal would mean that any portal could work; say, a custom one built out of # 89 glowstone or # 7 bedrock. Would mean that you could tie it onto custom gate mods, too.
