[Building Sakai] grade book / grade book 2 compatibility

[Matthew Jones]

Agreed, both of these use the same basic data model, however there are some
features that are may be present in Gradebook2 (or even in Gradebook) which
aren't implemented in the other. So if one class was using both tools in
the same site the calculations could be wrong. The one I know that was
different was drop highest and lowest. This was for sure implemented
differently in GB1 verses GB2. It wasn't even present in GB1 until 2.9.

GB1 in trunk also has some features for extra credit (
https://jira.sakaiproject.org/browse/SAK-21225 ) and GB2 also has these but
implements these differently so like Bryan said if you're using one of the
tools in one particular version of Sakai you might see one set of scores
and another set in the other tool, which can be very confusing for
students.

At Michigan we'd generally strongly recommend that if an instructor placed
Gradebook2 that they remove Gradebook. I even wanted to put up a warning
message on both tools that notified the instructor pick one and either hide
or remove the other if both were placed.
