Attach tools to mouse Support

[EnnioEnnio]

As a smalltalker with the option "attach tools to mouse" enabled I want windows opened with Algernon also to be attached to my mouse and thus not being disturbed in my workflow.

Since Algernon aims to make Squeak more keyboard centric it would make sense to me if this is only the case, when I click the Algernon-suggestion with my mouse. Opening a window with pressing enter should stay the way it is.

Adding optional support for also having this feature when pressing enter on the keyboard would be very useful.
