After merging the cross plot with the summary plot, the sources stepping can be simplified. Remove obsolete sources stepping code, to prepare for other source stepping issues.
* Support cross plot in plot templates
* Fix source stepping for cross plots
* Show cross plot data in "Show Plot Data"
* Use bin size and realization count when computing cross plot statistics
* Update titles after dropping vectors into plot
* Do not replace _Name variables
* Make sure signals are wired when opening a project file
* Add auto name field and set default on
* Remove includes from header files
* Ensemble plot templates now have .erpt extension and new icon
* Default plot templates are given a checkmark overlay on the icon
* Context menu has been cleaned up a bit
* Old default template is really just the last used template. Rename it.
* Add max. recursive depth setting in preferences for plot template searches
* Only create plots based on correct template type when importing ensembles or single cases
* Support creating new plot from template explorer
* Update last used template when creating a new plot from a template
* Add summary default plot type selection in preferences
* Create plots as set in preferences when loading summary cases. Allow selecting default plot templates from templates explorer tree
* Do not create plot if data vector setting is empty
Remove obsolete single summary template code
Always use maximized state of the QMdiSubWindow when a plot or view is deleted.
Move time axis to top
Set correct text for unused axis
Avoid assert when layout is requested for non existing legend
* Remove obsolete template commands
Use first object in object list when creating plots for templates and a case is selected. (use first well in well list, first group in group list, ...)
* Always create the reference string
* Deprecate single summary plots and plot collections. Replace functionality using summary multi plots. Clean up some code. Fix crash when trying to normalize an empty curve
* #8425 Multi Graph : Support grouping on object name
* #8425 Multi Graph : Improve creation of new graphs
* #8425 Multi Graph : Improve default tick mark count
* Handle history and non history as identical headers
* #8425 Multi Graph : Increase space below a graph
