Drop lowest displays incorrect points when you drop more points than you have

Description

Basically subject line says it alls.

The case this issue showed up in was with a Categories/Points gradebook. Set up a category with drop lowest higher than the number of effective items in the category. Then the points displayed will be incorrect.

For example if you have a gradebook with 7 items with a drop lowest set to 80. Initially you will get a proper #.

Now reduce the number of items by setting individual items to be not included in grade. The points will then become incorrect.

So will this be an 1.8.0-a9 fix? If so lets change the Fix Version to reflect this.

Test cases:

Setup category with 3 items.

With drop lowest of 0 and all included, then category points are at 300.
Incrementally increased drop lowest to 4 drops. Category points decreased appropriately and was at 0 points for 3 and 4 drops.
Incrementally changed items to excluded. Category points value remained at 0 for each exclusion.
Leaving all items excluded, incrementally changed drops back to 0. Category points remained at 0.
Added new items until I had a total 8. Category points remained at 0 until the 8th item was removed. (3 excluded and 4 drops.) Category points ended at 100.
Changed that 8th item to be extra credit and category points went back down to 0.

Unit tests passed. Will check code into svn.
