Compilation fixes for merge upstream 2.3.2.

The avatar functionality in
src/org/oscelot/blackboard/basiclti/extensions/Memberships.java was
commented out because MyPlacesUtil.displayAvatar() is apparently now a
hidden function according to Eclipse. This is compiling with the
Blackboard jar libs from SP11.

I've incremented the version number to 1.0.2 to indicate the merge.
