Sculpt Mode: Allow to limit the behavior of the 'Quick Toolbar' menu. (spacebar).

Hello.

In sculpt mode, the 'quick toolbar' you access with spacebar (or shift+spacebar depending on your settings), can have up to two behaviours.

Normal mode: It happens when you press and release the button. This provokes the tool bar to appear, stay, and wait until you select a new tool by clicking on it from the menu.

Quick mode: It happens when you press the button and leave it pressed. At the moment of release, it automatically closes and selects the tool you have the mouse cursor over, no matter if you clicked on it or not. This second mode uses to happen when you have previously used another tool.

I consider this behaviour a pain. It provokes chaos in my mind. I press shift+spacebar (i have configured so) and when I'm focused on the sculpting, I don't know/remember if the next time I call the menu, it is going to stay or to dissapear at the release of the spacebar. So sometimes the menu stays, and sometimes the menu flashes and closes instantly. It's very frustrating. If I press shift+spacebar and hold the spacebar always, it can provoke chances to activate the animation bar. So animation frames begin to count in the viewport and I have to stop them and restart the animation bar.

Please add an option to disable 'quick mode' of this bar. It would be cool if you can an option to make it behave always normally.
