Make icons match between the different location where they are fou

[Frozen]

Simple idea is to make the icons found in the palettes, the block diagram and help all match.

The icons in the columns are all the same function, however, there are some significant differences. It is reasonable to expect the help menu icons are expanded to show additional functionality, but there is no reason why the palette and BD icons should be different. The core of the icon in the help menus should be the same too.

These icons screen shots are from LabVIEW 2018.

sorry to beat a dead horse, but the deviations are still happening...
