#4817 #4830 #4832 #4837 #4839 Python commands for WBS creation, well path import and well log file import (#4838)
* Better minimum width for well log tracks

* Fix alignment of scrollbar in Well log plots

* Better Well Log Plot export

* Hide scroll bar before plotting
* Better borders

* Create plots through Python

* #4817 Create WBS plots with Python

* Rebase Summary and WellLogPlot on top of a new RimPlot

* Also Python: Allow setting folder as a parameter to export_snapshots

* #4832 Prepare for well path import command

* Well Path import WIP

* #4830 #4832 Import well paths and well log files from file using Python.

* #4837 Implement import of formation names in Python

* Fix debug build issue

* Fix RiaLogging build issue

* Fix warnings

* Yet another RiaLogging.h import added

* #4839 Import exporting of las and ascii files from well log plots
