Hotfix for the past few versions

Changed:

• Some End Gateway blocks replaced with Wormhole blocks in Arkemer Nebula dungeon. This made because End Gateway blocks causes freezings while there's too much of them

Fixed: 

• Arkemer Ageagoria Utopia block appeared in Time Travel dungeon once again
• Snifferino Blueberrino dialog was bugged
• Errors in Seraphim description
