Turned off testing on CG size B, C, and D as they time out and will continue to
do so until someone looks into improving CG.  Updated README.performance to
reflect this, and turned off graph generation for them so that no one gets
worried by us no longer having data for those problem sizes. [requested by Brad]

Turned off testing on EP size C and D as they time out and will continue to do
so until someone looks into improving EP.  Updated README.performance to reflect
this, and turned off graph generation for them so that no one gets worried by us
no longer having data for those problem sizes.  Also, modified the timeout so
that it was ~5 minutes.
