Makes some smaller changes

Replaces the mystery code in sendMessage with translateAlternateColorCodes and removes the TODO
Removes the TODO in deactivate() as it is actually necessary because fixed portals are always active
Moves conflictsWithExistingGate to PortalCreator and removes the TODO for now
Removes the extra spaces in >Random<
Adjusts some comments
Adds missing information about Economy and the requirement of UUIDs
