* Add Max7219 LED Matrix Debug Support
The Max7219 8x8 LED Matrix's are very helpful for debugging new code.
And for that matter, just trying to maximize printer settings without
causing stuttering.
The displays are very inexpensive (under $2.00 with shipping) and
provide a lot of help when trying to debug complicated code.
* Try to keep Makefile up to date.
ArduinoAddons has been removed from Marlin, remove any references to it.
Replace HARDWARE_SRC and HARDWARE_DIR with its expanded equivalents.

Instantiation of the static singleton instance thermalManager in general
requires locking, but we know its safe to do without.
Add -fno-threadsafe-statics to avoid using locking primitives, which
result in linking errors:
undefined reference to `__cxa_guard_acquire'
undefined reference to `__cxa_guard_release'

The PrintrBoard Rev F utilizes a mcp4728 DAC to set motor current. Printrbot's implementation utilizes 2 new M-codes to set and write the DAC settings to the DAC EEPROM: `M909` (Read DAC) and `M910` (Write DAC). `M907` is re-used to set value, `M908` for direct control.
The Pins file for the RevF board is included.
- also by default use ${HOME}/Arduino as install directory which may be more
sane, especially with arduino packages provided by distributions
- bump arduino version to 106 (this seems to be useless)
- program firmware through the USB serial which is more comfortable way how
to program the firmware
- use 57600 programing speed by default which seems to be more reliable
with arduino bootloaders (at least with those shipped with the Melzi2 boards)

Add beeper pin for Azteeg X3 Pro
Use "whole program" and "link time optimization" features of gcc. The
whole-program optimization enables the compiler to evaluate the entire
firmware for optimization instead of just one code file at a time.
This leads to better overall optimizations.
