WebPrarie di Sooraj

This addon changes multiple visual elements of PrarieLearn to be more readable, usable, and similar to WeBWorK. Some changes that this addon does:

1. Each separate line in the assessments page alternates in shades of grey to visually segment the different assignments.
2. The coloured boxes for the assessment type are now uncoloured as the colour is unnecessary.
3. The progress bars look more like WeBWorK and they are coloured based on the deadline for the specific assessment.
4. Some information is now hidden such as when as assessment has no credit available to get.
