After discussing with Susanne, I changed the patch a bit (attached v2):

The API function t3lib_befunc::helpTextArray now will return the
information "raw". The ExtDirect will do a strip_tags() and the old
helpText will do what it used to do (backwards compatible).

The "arrow" icon is now gone again, because currently *all* tooltips are
linked with the popup, even if there is no more information in the
popup. I think this needs to be changed in the future, because it is
annoying to click and expect "more information" and then there is
nothing new in the popup. This used to be the function of that "arrow"
which was the link to the popup.

Steffen Gebert, could you file an issue in the HCI tracker so that they
can decide how it should work?

Cheers,
Ernesto
