New IntensityDataWidget as a replacement of heavy IntensityDataPlotWidget. Corresponding icons are changed to their svg versions.

Simplified filter list in ImportDataAssistant to baypass MacOS reluctance against double extentions, like *.txt.gz

Temporarily disabled the possibility to have more than one links in FitParameterItem (waiting for redmine #1478)

resetView() responsibility is moved from ColorMap to intensityDataItem, fixed bug with wrong axes range when switching between axes units (nbins, degrees, etc)

New StatusLabel class which is intended for auto resizing depending from size of surrounding layout.

New ColorMapCanvas class which intended form embedding of CalorMap and controling its (font size, status string)

ColorMapEvent finnally constructs status string which is convenient to use in higher level IntensityDataItem widgets.

New light version of ColorMap to provide plotting only, without heavy functionality related to projections plot.

Important: commented one expensive line in qttreepropertybrowser, while fighting for ComponentEditor performance
