This is a bugfix release. It attempts to prevent bootloader corruption

by turning on the Brown Out Detector.

No changes in the electronics.

New features:

- Supported EDA toolchain is now gEDA 20100929, the one coming with
  Ubuntu 11.04.

- Use stronger 2 pin, 4 mm connectors (same type as the motors) for
  the heaters. These match the required currents much better.

- Remove the MOSFET for the fan. Only few people use a fan. If
  you're one of them, connect the fan to the PSU directly.

- Remove the I2C header. Was totally unused.

- Make thermistor connectors 2 pin only. The extra pin just caused
  confusion.

- Replace the ATX20 with an ATX24. The new header is compatible with
  more recent PC power supply types and accepts ATX20 plugs just fine.

- Use another disk power type connector to supply the heaters. This
  allows to run a heated bed directly off the Gen7 board, without
  relays in between. This also introduces the ability to use different
  voltages for motors and heaters, without making things more complex
  for casual users.

- MOSFETs are now upright, for better cooling and mounting a heatsink.
  Also inserted a matching heatsink to the parts list.

New features:

 - The Endstop now uses the TCST1103/2103 photo interrupter.

New features: fix all those silly 1.0 mistakes.

New features: it works. Isn't that the most important thing on an 1.0…
