Open project in new window confirmation

[stevemessick]

Android Studio ignores the preference that asks whether to open a new project in a new window or in the same window. It simply opens a new window (which is what I recommend, especially for add-to-app projects). We should confirm this is intentional and, if so, change our project creation code to match.

Clarification: project creation does not ask about multiple windows but re-opening an existing project does.
