Update README.md
Rewrote LPD8806 Ethernet sketch based on etherCard

This rewrite removes the dependency on the Adafruit LPD8806 library, because while it is useful, it's also a waste of resources for this particular application.

The etherCard libary makes the sketch itself significantly easier to read, removing the old packetloop to a single library funcion that seems comparatively massively optimized with regard to memory.

The ethernet buffer has been reduced to the very minimum necessary for the application, clocking in at 534 bytes.
Quick hack on the python demonstration script

Added commandline option and flag parsing to target host, port and strip length. Fixed a few variable names and slightly optimized code
Rewrote a few functions to be more self-explaining.

Functions now adhere to a camelCase typing which was mostly but not strictly adhered.

LPD8806.show method improved for better readability.
Re-ordered class and functions in color module and added small docstring.
Added pinout/hardware connection documentation.

Added chipselect constant to sketch for easier changing by user.
Removed explicit SPI library reference.
How many LED's? Quite a few!
Placed try/except on the correct level.

The try: statement is now on the inside of the loop. This means that if a single position is missed but there are more to come, these will also be accessed. That is, if only LED 4 (out of 160) is not present, the old could would place 'AAA' on the fourth position and then stop. The current code places 'AAA' on that position and carries on processing the following 155 LED's.
