add a navigation indicator for table rows

[erwindon]

Is your feature request related to a problem? Please describe.
clicking on table row has various effects: it may navigate to a details page or it may show the cmd-popup.
for menu items it is less obvious since the description already gives a clue and the "..." shows that a popup will be used.
with the introduction of #574 that becomes less obvious

Describe the solution you'd like
add a i-icon to each table to show what will happen when you click on a row of that table.

Additional context
see #574

[erwindon]

add a i-icon to each table that (on-hover) shows what will happen when you click on a row of that table

this function is added.

@rcmoutinho
have you tried it?

everyone:
any hints on how to show this for the items op a popup-menu are welcome!

[rcmoutinho]

So far, it works fine for me. I made just one comment so you can double-check on your side.

[erwindon]

split this in 2 parts, one for table-rows (this one) and one for menu items (#579)

I changed the style of the hint from a (?) icon to the style that is also used for panel-related help (but a bit smaller)
