Create separate target for moving mlpack headers. This should fix #322 .

Move LaplaceDistribution to mlpack::distribution and expand upon it, but then
...
remove MoveDistributionType template parameter from SA class because really, the
MoveControl() function is written specifically to work with the Laplace
distribution. I was incorrect to think it could be templatized so easily. The
implementation of the Laplace distribution has been inlined, too, which may help
it be a little faster.

Significant refactoring of NMF tests. The sparse tests were generally invalid
...
because NMF is not guaranteed to produce a unique decomposition. Instead, now
we test the Frobenius norm. Also, the tolerances needed to be significantly
adjusted because of the new convergence criteria in the AMF class. Lastly, the
SparseNMFRandomDiv test and SparseNMFDefaultTest have been removed because those
update rules seem to often result in NaNs when sparse matrices are used as
input.
