[IMP] sale_timesheet: SO/INV stat button on project overview

Now that the overview is refreshed when it is displayed and that we
can create SO/INV from it, it is usefull for the users to have
a stat button displaying those new documents directly from
the overview.
This commit use the already existing mecanism to display
Sales Order and Invoices stata buttons.
Thoses 2 stat buttons are only visible for salesperson seeing
all document, to avoid access errors.
