Cannot delete purchase orders (trunk)

[Dukai Gábor]

Hi!
Trunk version.
Please review purchase_order.unlink(self, cr, uid, ids) because it needs a different argument list. Trying to delete a purchase order the following error appears:

Traceback (most recent call last):
  File "path/bin/osv/osv.py", line 59, in wrapper
    return f(self, dbname, *args, **kwargs)
  File "path/bin/osv/osv.py", line 119, in execute
    res = pool.execute_cr(cr, uid, obj, method, *args, **kw)
  File "path/bin/osv/osv.py", line 111, in execute_cr
    return getattr(object, method)(cr, uid, *args, **kw)
TypeError: unlink() takes exactly 4 arguments (5 given)

This has been fixed already.
Make sure you are using latest version.

Thank you.
