FEATURE REQUEST: Shorten default printable representation of activities

Hi alphapapa:

As an example, if I resume an activity with just 2 windows to restore, in the minibuffer I see this massive print construct which is good for a developer of the activities.el package but too noisy for a user. Maybe you could add a debug flag that would turn on such details but have another representation where largely just the buffer names to display were shown. This is another instance where working with activity names rather than the associated objects could help. Thanks.
