make s3 chosen if no config option specified

rename *wrapper  to FilestoreManager
remove ToS3 from filestore commands
rename configuration option for filestore.
add details of interface to FilestoreWrapper.coffee for reference.
remove api comments
rename settings.filestoreManager to settings.persistorManager
