colorouring log entries

[MangoIV]

It would be nice that for each process, there would be a color that signifies that particular process, i.e. the name somePackage> would be coloured in one of |--cores| colours.

One problem of this is that we would probably quickly run out of colors and we would drag in a ratstail of having to implement colourschemes and such.

For vision impaired users, this should at least be opt-out.
