[FIX] tools.translate: when loading entries from a PO file, use also the POT.

On Launchpad, as commented on lp:933496, PO entries (andtheir comments) are
shared between series. This mean that e.g. the 6.1 series can have the wrong
`reference` comments (those beginning with #:) as they would be copied from say
the trunk series.  Those `reference` comments are used by OpenERP to create its
translations and look them up.

This patch adds a few lines of code to tools.translate.py so that targets
defined in the POT `reference` comments are used in addition to those from the
PO file.

Fix log message
[IMP] Improved reporting of test failures
            
While loading modules with the tests option, it's useful to have a report that
display test problems separately from the main log. It's then up to the
launching system (for instance openerpcommand) to produce meaningful user
output.
            
This would ease I hope the maintainers task in case of regressions by letting
them dispatch easily to people that happen to know the relevant modules
(together with the author of the commit that triggered the error)
            
A corresponding patch for openerpcommand will be uploaded
