Added schema-after-0.9.0013.sql extracted from flxtest.bodytrack.org.  Did some comparison with schema-after-0.9.0012.sql which was generated from Candide's instance.  In some cases where schema-after-0.9.0012.sql diverged clearly from the original schema + successive sql changes I tweaked schema-after-0.9.0012.sql to be more consistent.  Gave up after a while and just let the one from flxtest stand as is.
