Merge branch 'master' of github.com:SpringSource/spring-batch into BATCH-1960
Made changes to generate-sql.  Do not understand how we copy from
generated-sources to /src/main/resources but the generation has fixed
all of the same bugs that were manually fixed in /src/main/resources
including the preferred approach, drop contraints for postgresql.
Failed to add all of the files in the previous commit.  These are the
other additional changes made.
