#38 better name for the output "found?" for "Read Key (Variant)__ogtk.vi"

[s.hb.]

The VI Read Key (Variant)__ogtk.vi should have a better name for the output found?.

Suggestion: found all?
Reason: It is only true when all parts have been found (every cluster element, ...)

Additional:

add a new output found any?, which is true when any element (of a cluster, ...) has been found. (operation OR where found all? has AND)
