Add 2BPP helper functions for our blocks.
...
Namely, there are two things that we need to do:
1. Figure out the sub-mode based on the mode bit and the structure of the modulation data. The comments in Block.h describe how we do this.
2. For a given texel index, return 2BPP texel modulation bits.

Add a working directory for PVR lib tests
...
Unfortunately, the WORKING_DIRECTORY directive for ADD_TEST seems to be broken as of CMake 2.8.10, fortunately there was a mail thread about this issue in 2.6 so I was able to implement the workaround.

Add PVR tests
...
If cmake was able to find Imagination's PVR library, then it'd be nice to make sure that our decompressor matches theirs. We incur a bit of overhead by adding .pvr files into git, but hopefully this cost will be beneficial to actually figuring out how things are working...

Abstract away some utilities that we can use across all of our tests, and add a test for a gray image. The test currently seems to be failing, which is likely due to a bug in our bit depth manipulation code.

If all of the PVR blocks are the same then we don't need so much code.
