Change NSHMP Utils classes to use Streams instead of Files

[Kevin Milner]

Peter's NSHMP Util classes use class.getResource(...) but then convert it to a File object, which won't work with resources in jar files (thus won't work in our applications). I started to replace it, but it uses some File object specific library to do the parsing so I'm going to leave it up to Peter. Until then, I've disabled the FrankelEtAl_1996_AttenRel IMR (set it to new DevStatus? state called "ERROR"). The ERFs are still included, but will only work when run via eclipse.

I also had to disable the CEUS IMR because it uses Frankel 96

All resource references have been updated to use URLs and Streams instead of files. I've left AttenRelRef? alone for now.
