Issue-#175 Display StdLink command in status line

[Josef Templ]

Sorry now we have another nasty bug. It is not possible position the cursor inside a target by clicking the left mouse bottom.
- Helmut

The observed behavior resulted from treating Links and Targets in exactly the same way.
But I agree that this is questionable for Targets because
(1) it differs from the BB 1.7 behavior and
(2) there is no action associated with simple mouse clicks.
I have restored the BB 1.7 behavior for simple mouse clicks on Targets now.

I think we can proceed with the voting about this issue.

Do we need a voting at all or can I just merge it to master?
Are we waiting for something else? For what?
