Add manual and by-pointer window placement

This adds a window placement preference: the existing behavior is now
called "automatic" and is the default. Two new modes are being
introduced: "pointer", which means that windows are placed according to
the mouse pointer position; and "manual" which means that the user must
manually place the new window with the mouse or keyboard.

This is a straight port from muffin, commit 3257671.
