[New function] Managing multi customer project

[TuxPenguin72]

Today, project is linked to one customer.
In our activity, more than one customer can buy a project.
It would be great to link project to a number of customer.

I know this is an old issue, but the way to achieve this is to have no customer linked to the project itself, but to add the in the contact tab of the project.
