Updated SWIG interface files to reflect changes in project directory structure.
tempo: remove unneeded code
tempo: match python/octave code up to end of BH
Build fix for FindPackageHandleStandardArgs

Apparently 2.8.7 doesn't include this package by default?  adding
  include(FindPackageHandleStandardArgs)
fixes it.
tempo: clean up python implementation
tempo: add BP matlab version
Ported GStreamerSource to use GStreamer 1.0
Removed the #ifdefs which became unnecessary when GstreamerSource was moved into the 'optional' directory.
Added liblinear, a package for training and predicting with Linear Support Vector Machines to otherlibs.  Added SVMLinearClassifier.[h|cpp] but did not hook these up to liblinear yet.
Added nextract, a program that extracts features and outputs to a text file
Changed nextract to be simpler and to write out files in libsvm/liblinear input format
Small cleanups to nextract
Added ability to output the current time of the slice instead of the label, useful for predicting unknown data with libsvm/liblinear
Put texturestats in nextract.  This obviously helped the classification with liblinear a lot.
tempo: add doubling heuristic and SVM

Still something wonky with the BP calculation.  I thought it
wasn't so significant but it distorts the svm values quite a bit,
so I'll go back and take another look at it.
core: MarSystem: add getter for controls map
marsyasqt: Marx2DGraph: add method to change data + dimensionality
introduce qt5apps: inspector
cmake: FindGLUT: handle standard args (like REQUIRED, etc...)
cmake: set QT_USE_QTOPENGL only where it's needed
