Send all activities for all projects in one email

[cforce]

At the moemnt for every project a own email is created and users which subribed for digest will get amount of project emails on day x.
Wouldn't it make more sense to send all activities for all projects in one email. For every project activity list, there shall be a own section (header).

I think this would be a great configurable option as there are good use cases for one email per project as well.
