dynamically color sample types

[romunov]

Right now, sample types are hard coded. This is not acceptable (work for our sample data right now) and the restriction needs to be relaxed.

The idea is that this should be some sort of a form, where user could change colors for sample types. For example, someone might fancy to color mortality samples with a bright red color.

I'm thinking maybe incorporating a settings page with colourInput drawn dynamically. Perhaps there's a better, more compact solution

I wonder, is it possible to change legend opacity to match that of the input/slider at the top right corner?

Adding a settings page and a tab for picking colors using colourpicker package should do the trick. Just have color mapping of sample types in a data.frame and update based on input$picked_color.

For some reason, I can't get solution using colourpicker to work. @charlie86 can you have a look at this? If you turn this on/off you will notice that the list does not work when TRUE. What's pissing me off is that it works when the list is created manually. I've compared outputs and I can't really find anything substantially different.

The problem was that I was using a limited palette for automatic generation of inputs and "square" for the manual one. Since limited palette doesn't hold brewer specified colors, it reverts to black. A warning would be nice...
