Made the necessary adaptations for the dashboard launch and fixed some bugs (already live).

Will now recognize warnings as a status. Returns proper HTTP status codes for the most common errors now. Will be more strict when checking build status data (no newlines in bot names).

Prepared cron scripts.

Prepared dashboard for production use.
