BUG: Fixing #777 - vcl_abs should NEVER be used on spacing when computing coordinates transforms: most georeferenced image will have a negative y spacing

ENH: Added OTB_VERSION_CHECK(M, m, p) macro to Configure.h.in; Conditionnaly enabled/disabled In/OutProcessXMLParameter in otb::Wrapper::QtWidgetParameterFactory.

BUG: MANTIS-750; ENH: Improved exception management (safer); Fixed dataset consistency missing checks; Fixed some multi-line translatable strings; REFAC: Cleaned debug traces; Fixed DatabaseBrowserController::CheckDatasetsConsistency() method-name typo.

BUG: MANTIS-725 (Replaced forgotten I18nCoreApplication::*SettingsKey(const QString&...) calls by I18nCoreApplication::*SettingsKey( I18nCoreApplication::SettingsKey...)).

ENH: Changed histogram-view trackerText() and drawRubberBand() to read visible curves only (ess RGB selector combo-box).

ENH: Added tooltips to zoom 1:1 and zoom extent of histogram; Changed tracekrText() format of histogram.

ENH: Fixed histogram-view grayscale problem (bad refresh of RGB curves when switching from saved grayscale-mode image to RGB color-setup).

ENH: Use of Scott's formula to compute number of bins of histogram; Cloned otbStreamingHistogramVectorImageFilter in order to upgrade interface (number of bins per band).

ENH: Fixed crash when ColorSetupController::ClearWidget(). Missing QCOMBOBOX_NAMES[] entry for RGBW_CHANNEL_WHITE.

ENH: Implemented HistogramPlotPicker::drawRubberBand() and ::trackerText() methods to pick (by dichotomy) RGB frequency values of histogram.

ENH: Docked histogram-widget; Added AbstractModelController::ClearWidget() when dataset selection is cleared.
