loadMelodicLabelFile currently assumes that ICs not in this list are
'Signal', which is not the case (they should remain 'Unknown', and
the included ICs should be labelled as 'Motion').

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.
