StripY CN; Y-axis control added for all plots; some Y-specific settings added.

StripY CN added. Axis control is separated for Y, for all plots. Cluster high threshold, high noise and high row noise threshold have been added in the settings. The Langaus fit ranges have been optimized for X and Y detectors. The fit results are displayed (display adapted according to the number detectors). Some useless code has been removed (still more to be removed). Introduction of 2 class attributes fNstripX and fNstripY.
