Fix indentation and remove trailing whitespace

This patch provides common/mekanism/*.java with standardized indentation (tabs) and also removes trailing whitespace.

To accomplish this, I used this [script](https://gist.github.com/vmrob/9423533) and then manually resolved the remaining problems in the following files:

common/mekanism/client/model/ModelArmoredJetpack.java
common/mekanism/item/ItemBlockMachine.java
common/mekanism/tank/DynamicFluidTank.java
