Add a new printer

Research

• Official full name of specific printer (check their store)
• X, Y, Z bed dimentions (all 0 for delta bots) (currently only used for centering drawing)
• Heated bed support
• Filament thickness: 2.89 or 1.75
• Custom start and/or end g-code? Prefferably not, since that complicates support and maintainance.
• Driver type: Marlin or Makerbot
