Balloon 4.2.0

• Fixed issue where dialogue on multiple lines moved left or right a tiny bit as each line appeared.
• Added always_on_top option (on by default) to render the final textures in an IMGUI window to ensure Balloon always appears in front of all other custom UI elements. If you have any problems with this you can switch back to the old rendering method using /balloon always_on_top but most people shouldn't notice any difference.
• Added in_combat option which is off by default and means Balloon won't open in combat. If you want Balloon to open during combat you can use /balloon in_combat.
• Some hyphen and punctuation fixes (thanks @Herschel).
• Fixed addon error that could occur when using additional_chat_modes (thanks @Herschel).
