Merge branch 'master' of github.com:PecanProject/pecan
Added more defaults to check.settings
changed db.query etc functions. now use db.open, db.close and db.query.
db.open, and db.query use settings as param
db.open might work with other databases (PostgreSQL)
db.open/db.close keep track of connections and print any left open connections (db.print.connections)
