Title: Removed decay data, now with pyne!

This PR replaces the decayInfo.dat file with nuclear data coming from pyne. A custom `cyclus_nuc_data.h5` has been created and uploaded to [our webspace](http://regtests.fuelcycle.org/cyclus_nuc_data.h5). The install process will automatically download and install this file. This data file may be generated by the following command:

```bash
scopatz@ares ~/pyne staging $ nuc_data_make -o cyclus_nuc_data.h5 -m atomic_mass,scattering_lengths,decay,simple_xs,materials,eaf,wimsd_fpy,nds_fpy
```

This PR also exposed what I would consider some fundamental problems with how the current methodology works. These will be addressed in separate issues as the purpose here is *only* to integrate with pyne data. As much as I wanted to throw my machine out of the 4th floor window of ERB during this process, the unite tests now pass :).
