Submit flags for non-down services first

[Kevin Hamacher]

The submitter should try to submit the flags for services which are not down, first. Currently, it just selects the flags out of the database and if the service is down, this will block the submission of valid flags of running services.

Fixes issue #18 Now flags won't be submitted if their service was marked as down in the last minute
