* Make sure loading of Cross plot from file works

* Show Legend in Cross Plot

* Uncheck / Check curves to disable/enable

* Axis titles and checkable data set

* Name config and setting of common plot look

* Fix category indentation in GeoMech results

* Support name configuration for Grid Cross Plot

* Support adding new curve sets

* Improve colors and symbols with better cycling

* Moved GridCrossPlot files to sub directory in ProjectDataModel and Commands

* #4111 3D calculations : Always show difference options

* Whitespace

* #4111 Move resultDefinition field to private

* Whitespace

* #4087 Ensemble : When importing and ensemble, show by default an ensemble plot

* #4085 3D view: Improve overlay item colors

* #4106 Crash on Linux

Temporary workaround to avoid crash

* #4106 Stop trying to do recursive setting tab order widget

* The double pointer was handled wrongly and shift-tab order isn't working anyway.

* #4114 Regression Test : Remove cached pointer to eclipse case

* Revert "#4114 Regression Test : Remove cached pointer to eclipse case"

This reverts commit f2146c6007.
