BBIM - Add 'calculate all quantities' and shortcut to Spatial tool

[jes-r]

Hi, as I wrote here it would be nice to have the shift+q option within the spatial tool, as we now have to switch to wall tool and do it there.

@maxfb87 thought this would be helpful too.

It might be an idea to add a 'calculate all quantities' button here too, so this problem is tackled for every element.

Just like this button that shows up after you have generated all quantities:

Thanks in advance!
