[a,b] concatenation is deprecated

[cormullion]

I'm seeing loads of these (my terminal's overflowing with warnings...:)):

WARNING: [a,b] concatenation is deprecated; use [a;b] instead

I think it's here:

if isodd(N)
    midcol = weighted_color_mean(0.5, pal1[end], pal2[1])
    return [pal1[1:end-1]; midcol; pal2[2:end]]
else
    return [pal1[1:end-1]; pal2[2:end]]
end

What's the fix - return collect(pal1[1:end-1]; midcol; pal2[2:end])?

Wasn't this fixed on master by #9 !?
I can't reproduce it anymore with diverging_palette(0, 360)
Maybe time to tag?!

Yes, I appear to have an older version, despite running Pkg.update():

- Colors 0.5.2

In my directory I've got:

.julia/v0.4/Colors/src/colormaps.jl

where it says:

if isodd(N)
    midcol = weighted_color_mean(0.5, pal1[end], pal2[1])
    return [pal1[1:end-1], midcol, pal2[2:end]]
else
    return [pal1[1:end-1], pal2[2:end]]
end

which doesn't match the current version.

Sorry for the noise. :)
