Mana Lens: Resistance

The Resistance Mana Lens featured in Botania increases a Mana burst can go without losing Mana. The default is 12 blocks before it starts to lose Mana, and this block increases this by 9 blocks and maybe a little more into the next block. So in total this lets a Mana burst go for around 21 blocks before losing Mana.

There is also one consequence, the Mana burst shall travel a bit slower.
