to VolumeLabel - intent is that it will be usable with non-melodic images.

arg. When a Notifier listener is registered, it can be specified to run
on async.idle (to avoid threading issues).

As an aside, I have just realised that there is a naming collision
between Notifier.notify and HasProperties.notify, for anything which
sub-classes both. I don't think anything does, but this will probably
bite me in the future.

more work (and documentation).

controlled by the usePixdim and plotMode properties are now performed
by the TimeSeriesPanel, instead of the TimeSeries class. This was done
because TimeSeries instances added to the list already had
scaling/offsetting applied, so it was potentially being doubly applied.
This is no longer the case, due to a new 'preproc' option in the
PlotPanel.drawDataSeries method.

Also added some melodic specific stuff to the OverlayInfoPanel.

Also fixed the overlay.guessDataSourceType to handle melodic analyses
that are located inside other melodic/feat analysis directories.

Also tweaked the new colourmaps.randomDarkColour function to be slightly
less dark.

now automatically sets a TR property, if it can find the data
file. TimeSeries scales melodic time series by this TR accordingly.
