Conditional cell styling in Configurable Reports

Conditional cell styling: allow contents of cell to be styled depending on value in that cell or another cell in the same row. This includes, but is not limited to: setting character color, setting background color, bold and italic style, replacement of predefined values with icons (using FontAwesome). This is especially useful for “heatmap” reports of course activity usage or in crosstab reports to call out unusual values.

1. Specific example: allow display of Module icon in place of Module type.
2. Example 2: display avatar image for a given user id.
3. Example 3: Display a value in red if it exceeds a predefined limit.
