[IMP] sale_timesheet: add profitability report analysis

This commit provide a real reporting tool
for project profitability: graph and pivot
views.
You can now have a look at cost and revenues
per project, so line, product, see which
project manager brings the more money, which
project costs many human time, ...

The project overview is based on this report
analysis to be consistent.

However, a change of computation for 'amount
invoiced' is introduced: we now based the amount
on the price_reduce of the SO line, and not from
the invoice lines. Also, once a draft invoice is
generated, the quantity is considered as invoiced
at the price of the SO line (no matter is extra
discount happens when validating invoices).
