Improved tooltips: Global settings

[Wolfgang]

Hello,

I am still happy that the tooltips have been moved from the Programmer's Toolbox to the UI editor.

Now when using them on a more regular basis it turns out that the programmer might grant the user the option to show / hide them. As a result, I would need to programmatically browse through all controls to change the respective parameter (the same is true for the delay time).

Hence I propose providing two new, more or less global attributes (these could possibly be panel attributes) that set the tooltip enable/disable status and the on/off delay times for all tooltips (on a panel).

This feature is not urgent as it can be implemented already now with some effort, but it might make code a bit shorter and simpler

The more 'urgent' tooltip requests are here...
