[FIX] report: overflow of long content in reports colums

When having a long, non-breakable, content
within a report column,
e.g. an invoice with a very long, pipe-separated, origin,
the content overflowed on other columns.

Set word-wrap: break-word; prevent this behavior,
and is not considered dangerous regarding the possible
side-effects on the design in the reports layouts.

In fact, we should even consider applying this change
on the webclient itself. A similar issue happens in the form view
when having a field with a long non-breakable content,
e.g. a long, pipe-separated orign in an invoice. Nevertheless,
we should avoid taking risks in stable releases,
and this change in the webclient should therefore be done
carefully in master release.
