This project is spaces, Forestry is tabs.
We should choose now if this project should stay spaces or become tabs.
I would like it to match Forestry, there are already mistakes where tabs and spaces are mixed.

I'm fine either way.

Alright I'll convert everything to tabs tomorrow around this time.
Make sure you have all your changes committed, because this could make merging a bit annoying.

Yep, I vote tabs :)

Why tabs?
Forestry repositories contains 4 spaces.

Forestry is also tabs unless there is a mistake somewhere.

Sorry, I looked at the code invTweaks:
