InGame GuildChat Font Fix

• Locks the chat text size in Blizzard’s built-in Guild/Communities window.
• Does not affect the font size of regular chat windows.
• Even if you later change the font size of the regular chat window, the Guild/Communities window will automatically be restored to the specified size.
• The setting is saved across logins.
