Adds -msse3 to CMakeLists to fix OS X Mavericks build on newer i7's
Fixes assumption that sampleWDMass will always be run with only WDs in the photometry
Updates settings to match the new naming scheme (singlePopMcmc)

Comments out the loading of priorMean[CARBONICITY], but doesn't actually remove it from the code. It's still useful/used by certain applications, so removing it would do more harm than good. Additionally, it will be available if we'd like to put a non-uniform prior on carbonicity in future
Removes fsLike printing (not useful)
Makes random seeds a bit cleaner

Makes all applications generate a random seed if none is given (or, technically, if the 0xffffffff is given)
Makes all applications print the seed only if it is randomly generated
Removes _seed from mpiMcmc filenames, as it caused more problems than it solved.
Modifies makeCMD to use the same gridding algorithm as margEvolve
Makes makeCMD use deriveCombinedMags rather than getMags

This causes makeCMD to report apparent (rather than absolute) magnitudes
Adds build_local.sh and PREFIX option for build.sh
