XTool - Successor of ZTool

[Cesar82]

You may only need to fix some bugs and fully reconcile old ZTool items so ZTool can be removed from CIU.

Before I asked KaktoR:
Why keep ZTool and XTool in CIU, if XTool is ZTool's successor? Does XTool have bugs to keep both in CIU?

Kaktor replied:
No XTool is better (only bug is that big data input does not get unpacked with oodle and lzo codec. All other codecs work).
ZTool for example don't support crilayla codec (which is mostly used in the "anime-like" games like DragonBall, OnePiece, Sonic and etc).
So if you like to remove one of them, then remove ZTool.
