Description

The game crashes on startup when using Tooltips together with ASJCore, because Tooltips depends on com.mojang.realmsclient.gui.ChatFormatting.
ASJCore deliberately deletes all Realms classes (via RealmsDeleteTransformer), which leads to a NoClassDefFoundError.

Steps to Reproduce

1. Install Forge 1.7.10
2. Add your mod
3. Add ASJCore (with default config, where deleteRealms = true)
4. Create new world
5. Mine dirt
6. Drop it
7. Crash!

Suggested Fix

Replace usage of:
import com.mojang.realmsclient.gui.ChatFormatting with import net.minecraft.util.EnumChatFormatting
