Halve chase speed

description:	halves currently chase's BPM rate
remarks:	The problem with this code is that it requires the chase to be set as the selected playback in the editor (used for the Edit Times menu). This means that the Playback View which could be showing a cue list switches to show the chase instead, to get around this I have stored the previous selected playback and restore that afterwards but this does cause the display to flicker.

affected properties

This macro works perfectly well in Titan 9.1, does misbehave in 10.0 (always sets speed to 1 BPM), and throws an error in 10.1 (variable not registered).
