Add color options for analyze tab's column and bar charts

[PeterKnoop]

It would be helpful to have some very basic color options available for the column and bar charts displayed under the Analyze tab, such as the ability to choose a single-color for all of the columns/bars in a chart or to be able to specify the color used for each individual column/bar.

For example, if a question's answers are a color, it is currently confusing -- and potentially misleading -- when the chart displays the names of colors with symbols that do not match those colors, as in the following example:

Being able to set the individual column/bar colors manually, or being able to choose to use a single color for all of the columns/bars in the chart, would help avoid those problems.

This would help with quick visualization when others expect things in certain colors (for example, here in the U.S., Yes - green and no - red)
