Different label colours

[TimRepke]

At the moment, all denotations have the same colour. For better readability, the type should define the colour of that denotation.

I haven't decided on the best approach to this issue yet, but would like something that requires the least amount of configuration when setting up an annotation task. Colours should be applied automatically and should be deterministic (always the same for the same label), so having a "hash function" that maps label to a hex colourcode would be perfect. After that is as simple as changing a few lines where the colour for a denotation element is set:
