Update the pin layout table and consolidate the RPi readme files.

 - Changes in the pin layout table to describe how to connect the NRF24L01 pins to different boards
 - Remove duplicate readme information in the RPi readme file and point to the default RPi/RF24/readme.md file.

-# Optimized Raspberry Pi RF24 and RF24 Network Libraries  
-
- General Documentation: http://tmrh20.github.io  
-   
- Library functions are mostly the same.  
- See the included examples for RPi specific usage  
- 
-## Raspberry Pi - PreConfig
-    
-### Possible pre-configuration:  
-If SPI is not already enabled, load it on boot:   
-
-    sudo raspi-config  
-
-A. Update the tool via the menu as required  
-B. Select Advanced and enable the SPI kernel module      
-C. Update other software and libraries:  
-
-     sudo apt-get update  
-     sudo apt-get upgrade  
-
-
-# RPi - RF24 Quick-Start  
-     
-A. Make a directory to contain the RF24 and possibly RF24Network lib and enter it:  
-
-    mkdir ~/rf24libs  
-    cd ~/rf24libs  
-
-B.  Clone the RF24 Repo  
-
-    git clone https://github.com/tmrh20/RF24.git rtemp  
-
-C.  Copy the RPi library folder to the current directory, and delete the rest  
-
-    mv rtemp/RPi/RF24 ./  
-    rm -r rtemp  
-    cd RF24  
-
-D. Build the library, and run an example file:  
-
-    sudo make install
-    cd examples  
-    make
-    sudo ./gettingstarted  
-  
-
-# RPi - RF24Network Quick-Start  
-
-A. Enter the same directory that contains the RF24 library folder  
-
-    cd ~/rf24libs  
-
-B. Clone the RF24Network Repo  
-
-    git clone https://github.com/tmrh20/RF24Network.git ntemp  
-
-C. Copy the RF24Network folder to the current directory, and delete the rest  
-
-    mv ntemp/RPi/RF24Network ./  
-    rm -r ntemp  
-    cd RF24Network  
-
-D. Build the library  
-
-    sudo make install
-    cd examples  
-    make  
-    sudo ./helloworld_rx   OR   sudo ./helloworld_tx  
-  
-
-# Connection Info
-
-Using pin 15/GPIO 22 for CE, pin 24/GPIO8 (CE0) for CSN
-
-Can use either RPi CE0 or CE1 pins for radio CSN.
-Choose any RPi output pin for radio CE pin.
-
-**Constructor:**
-
-    RF24 radio(RPI_V2_GPIO_P1_15,BCM2835_SPI_CS0, BCM2835_SPI_SPEED_8MHZ);
-    or
-    RF24 radio(RPI_V2_GPIO_P1_15,BCM2835_SPI_CS1, BCM2835_SPI_SPEED_8MHZ);

-See http://www.airspayce.com/mikem/bcm2835/index.html for BCM2835 class documentation.  
-Note: The BCM library has been customized slightly to allow use of hardware CE pins not
-in use for SPI, and to include a millis() function.

-****************
-  
-Based on the arduino lib from J. Coliz <maniacbug@ymail.com>.  
-the library was berryfied by Purinda Gunasekara <purinda@gmail.com>.  
-then forked from github stanleyseow/RF24 to https://github.com/jscrane/RF24-rpi  
-Network lib also based on https://github.com/farconada/RF24Network
-
-Currently optimized and aligned with Arduino fork of libraries by TMRh20:  
-https://github.com/tmrh20/RF24/RPi and https://github.com/tmrh20/RF24Network/RPi  
-Documentation: http://tmrh20.github.io
