Update regexes to correctly parse version information for older versions of Armadillo.

First pass at version requirements for Armadillo. One thing left to do; when looking at version.hpp (not arma_version.hpp) the syntax is different, so I need to rewrite the regular expressions.

Fixed optimization/lbfgs/lbfgs_impl.h & optimization_utils.h so that they use std::pow instead of math::Pow. Also added a cmath include in fastlib.h

Remove some amount of debugging output. Fix DeflationLogCoshUpdate_() (was missing a "- n" term) so that FastICA now performs nearly identically to the trunk implementation.
...
Sometimes signs of output components will be different, but any other differences are trivial; it extracts independent components successfully.

Improve speed of AllkNN methods by using new armadillo mat::unsafe_col() method (returns an arma::vec alias which uses shared memory from the matrix).
...
The code now requires armadillo-0.9.90, since that function was new as of that version.

naive_bayes compiles now. Currently untested. Could also possibly use some cleaning up still.
...
Changed out Matrix -> arma::mat, Vector -> arma::vec, added std::vector where appropriate. Some std::vectors might should be changed to arma::vec.
No longer need math_functions.h for this.

FastICA now compiles, but I'm sure it doesn't work, and it hasn't been tested. The vast majority of methods from lin_alg.h have been pruned as they are no longer necessary.

Extend functionality of Armadillo; cov() operates like Octave, but what we want is
...
cov(trans()). However, that incurs a speed penalty with trans(), so I wrote ccov()
(column-based covariance) which does what we want without that speed penalty. I'll
submit the patch to Armadillo sometime, but for now we'll just include it with
arma_extend.h.
