rall. and accel stopped working in articulate.

According to the the git logs, in February 2011 the way that tempo
changes for MIDI were interpreted changed from just the
tempoWholesPerMinute property to use a TempoChangeEvent.

This broke rall. in articulated MIDI output.

This patch brings the articulate script up-to-date wrt to the way that
tempo changes are signalled, and also adds accel. and poco accel. to
the list of accepted scripts.

Correctly calculates stem-begin-position for merged stems.

Previously, the lookup for stem-begin-position was potentailly
triggered before note collision resolution occurred, which meant
that it ignored Y_AXIS shifts from collision resolution.  Now, through
using pure property lookups, stem-begin-position is not set until after
the collision resolution takes place.
