Borgerson, Matthew A 2255bc10b0 Enable basic framebuffer text console output
This patch simplifies the GraphicsLib code and adds an abstraction layer
for printing to a virtual "console," through the familier
ConsoleWrite(buffer, len) style function call.

ConsoleWrite can be configured to output to either the serial port, or
the display framebuffer, or both. This primarily enables the command
shell to be used with a display and keyboard.
