[FIX] for uncentered "dim." in piano-dynamics.ly template

[kwhite+lilypond]

The following fix (obvious once you know!) is required in the
piano-dynamics.ly template so that "cresc.", "dim." etc. are also
centered along with hairpins and dynamics.  This should allow the
use of "\setTextCresc" without surprises...

In other words, DynamicTextSpanner also needs an extra-offset.
