Some modifications to the PeaksWorkspace. Outputting Qx, Qy, and Qz to a PeaksWorkspace from the instrument view. re #3173

Refs #3175. Add a MatrixProperty that will allow Geometry::Matrix objects to be passed into algorithms. Also renamed the MantidMat typedef to DblMatrix so that it's clearer what the thing actually is.

When fitting upgraded output of chi-squared from info to notice. Also in this context improved the text used for outputted the quality of the fit. re #3166

OrientedLattice exposed to python. Check if U is proper rotation. Partial fix for LoadIsawUB. Refs #455

refs #2574 - added rebin option to "Indirect Diffraction" interface so that it can be used with IRIS data.

Kill the error messages from LibraryManager that appeared when Mantid started up with the plugins directory pointed at the bin directory. The real trouble was that Poco::Path().isDirectory does not actually examine the disk as to whether something is a directory, Poco::File().isdirectory() does this. Also cleared a compiler warning and a warning message on MantidPlot startup about a QWidget already having a layout. Fixes #3170.
