Link between sales and projects

The opportunity and sale workflows can be used to manage the quotation of services, which will be manually converted into project and tasks latter.

I think it is wrong to use sale order for project management. Sale order are designed to be a one time operation.

@pokoli

Add an sale as extra dependency on the project_revenue module.

Indeed I think it is better to have the sale_opportunity to be able to create a project (not sure it will be flexible enough). Or at least being able to convert it (link) to a project instead of creating a sale order.
