Vector display in results tab

[DanicaSTFC]

• Closes vector display after pointcloud #176
• closes Not all vectors are displayed #177

These have both been tested to be working correctly and displaying all vectors and points when the button "View vectors" is clicked. Probably this was a nice waterfall effect of #270.

• Replaced "View vectors" with "View:"
• Added extra lines (section) for viewing vectors and vector settings
• Moved 'subvolume size' and 'points in subvolume'

TESTS:

• Tested by running the app on magma data.
• Tested the view point cloud, view vectors, the scaling vector, and min max values.

NOTES:

• "On results panel, if you don't view pointcloud before viewing vectors, then the vectors do not display correctly." This does not seem to happen anymore.
• It does NOT Remove "View pointcloud/vectors" button.
  The 'View' button is connected to _DVCResultsDisableRanges, hence it is tricky to delete the view button until the checker is removed. Opened issue about this.
• Options underneath view vectors is STILL clickable if "View pointcloud" is selected. This is, again, not done because there is a checker on the min value which is tricky to remove.
• all points are listed in the widget "points in point cloud". This is not true if the push button view vectors is removed.
