Issue description:
I didn't have time to try to reproduce this issue in the latest versions, but if it's what I think it is I'm confident it still works.
If you chunk-load chunks in an RFTools Dimensions dimension, the RFTools Builder still works after the dimension loses power.
While this is not necessarily a "bug", I think it could be considered an exploit, or at the very least I don't think it is intended behavior.

Note: This is in a slightly modified FTB Revelation 2.2.0 server.

Question: Do RFTools Dimensions stay chunk-loaded entirely while powered, or is chunk-loading necessary for mining while not present in the dimension?

Steps to reproduce:

1. Build a dimension (I built an ocean world with gasoline oceans)
2. Go to the dimension
3. Set down an RFTools Builder with a clearing fluid shape card.
4. Define the area the shape card will work in.
5. Chunkload the area (I used FTBUtilities)
6. Start the builder
7. Unpower the dimension

The builder will continue to pump out the fluid in the chunk loaded area even after the
