Issue Description:

Burn rate shows with octatic capacitor in stirling generator as: 1,3333334x which seems incorrect.

What happens:

Burn rate is 1,3333334x in stirling generator(when using octatic capacitor) without capacitor it shows 1.0x(which seems more logical then 1.3333334x)

What you expected to happen:

It would be logical if the burn rate followed the same logic, as without capacitor, for example 1,4x or 1,3x instead of 1.3333334x

Steps to reproduce:

1.Get EnderIO 424.
2.Place down stirliing generator with octatic capacitor.
3.Look that it shows 1,3333334x instead of round number.

Affected Versions (Do not use "latest"):

• EnderIO:beta 424
• EnderCore:beta 0.2.0.21
• Minecraft: 1.7.10
• Forge:1614

The value is correct per se (1.333 is 4/3), but formatting… that can be improved I believe.
