Patch from Joe Atzberger that does several things:
1. Iniatial API calls for managing EDI documents at the server. EDI file fetching script to come soon.
2. Creates OpenILS::Utils::Cronscript and Lockfile modules to share and abstract the common setup tasks for Evergreen cron jobs
3. Creates a OpenILS::Utils::RemoteAccount module for managing access to remote services via ftp/scp. This is mostly taken from the SendFile reactor
4. Updates sendfile to use remoteaccount
