Add achievement that will modify reduced scoring.

This adds achievements that modify the reduced scoring time period while
leaving other settings alone. These are designed for classes which use
reduced scoring and keep assignments open in the reduced scoring period
for a long time (such as the end of the course).

+ ExtendReducedDate -> Extends the reduced scoring date 24 hours.
+ SuperExtendReducedDate -> Extends the reduced scoring date 48 hours.
+ NoReducedCred -> Removes the reduced scoring flag on an assignment to
  allow full credit after the reduced scoring date.
