Preview update/Menoth tier fixes

Fixed:
* Warpwolf stalker
* Shea tiers
* Diretroll bomber
* Titan sentry
* Missed the steelhead riflemen
* Rezniks Tier 1 also reduces the cost of the Reckoner Jacks by 1.
* Epic Severius's tier list breaks when you add the Covenant of Menoth - which is required for tier 2.

By the way, I always forget to mention this, but thanks all for the feedback! It makes this tool work.
Sadly I do not really have time for bigger updates at this moment, but I still hope you are happy with it!

Here are the menoth tiers!

Finally the menoth tiers are done! Note that they are in beta, so please please let me know if you find anything wrong with them. The tiers are kind of hard to do because of all the countless options and also we are trying to get my house ready for my girlfiend to move in which take quite some time. Enjoy!
