Added ```busNo``` passing to mraa::Spi()... per @prophet-roshak suggestion to SPI.begin chagnes

Added ```busNo``` passing to mraa::Spi() object creation call so that SPI bus number now can be defined by user when instatiating RF24 object

- Add Template folder with example class declarations etc
- Add template info to modules section in doxygen
- Update related links etc for doxygen in RF24.h

- Change SPI API for Linux devices to specify bus number in
SPI.begin(0);
- Enable kernel to handle cs toggling with SPIDEV
- Comment out GPIO for CS pin with MRAA
- Prevent linux devices from toggling CSN in RF24.cpp
- Ensure all linux devices default to 0 or 1 for csn_pin
- Remove some #ifdefs from RF24.cpp via above changes

- Note: When using SPIDEV, if the pin used for CSN has been toggled via
GPIO, users may need to do the following, to enable the kernel to toggle
CSN:
``` sudo modprobe -r spi_bcm2708 ```
``` sudo modprobe spi_bcm2708  ```

- Code needs cleanup/review

#69 #74

- Add Portability section to docs
- Add source file browser to docs
- Filter out GPIO and SPI classes from docs, but include in file lists
- Update doxyfile

- Modify spidev writes for bbb/linux - Something seems to have changed
with spidev with the spi_ioc_transfer struct on my machine. This seems
closer to the spidevtest.c example, so hopefully keeps working???
- Prevent warnings via compatibility.c/.h
- Add spi.begin to align with RF24 spi functions

Inadequate testing appeared to indicate the CRC checking was at fault,
this was incorrect.

Seemed to be 2 separate bugs in transfer example:
Symptoms: Arduino would start reading 150+ KB/s and about 5000
payloads/second received after a period of time with transfers ongoing
continuously.
Fixes:
1. Remove the printf of Payload Count (same issue with %lu )
2. Prevent division into 0

- Move some optional parameters to advanced operation and vice-versa

All documentation to be contained on http://tmrh20.github.io

- Move all documentation out of github.com readmes and onto github.io
pages via source code/doxygen
- Update Transfer example (16-bit CRC)
- Update ATTiny example (pin configuration)
- Add readme files to clarify old/non-updated examples
- Add/Update documentation for various platforms
- Deleted old RPi folder under RF24/RPi/RPi

Beginning of documentation updates for coming changes, and the
consolidation of info from readme into source/doxygen
Still needs lots of work..

MRAA: Updated memory usage

Fixed issue with ARDUINO not issuing CS for radio

- MRAA support originally by @prophet-roshak #74
- Updated to migrate support files completely into arch/MRAA and
minimize changes to the source files
- Changes as per suggestions from @arfoll

- incorrect define prevents dual devices from sharing the SPI BUS

- Update littlewire makefile by @lnxbil for new hardware support
template

- Update main Makefile (CCFLAGS)
- Update examples_RPi Makefile (CCFLAGS)
- Update examples_RPi/gettingstarted.cpp with BBB/spidev pins example

https://github.com/TMRh20/RF24/commit/e2abd640a296e1be9b2abc0d27bbd5caa1affa78#commitcomment-9750201

Move to new template for:
- RPi (BCM2835)
- BBB (SPI_DEV)
- LittleWire

RPi can be forced to use SPIDEV by calling "sudo make install
RF24_SPIDEV=1"

Potential RPi 2 support via updated bcm2835.c (version 1.39)

- Created the appropriate files for Due and ATTiny under arch/Due and
arch/ATTiny
- Modify RF24_config.h to suit the new changes
- Modify detection for Arduino Due ( ARDUINO_SAM_DUE )
- Update RF24.cpp for cleaner Due detection

Due changes are tested and working
ATTiny changes compile but are untested

Merge master with updates branch

Some changes to get different revisions of NRF24L01+ modules working. by @dsbaha 

- remove additional toggle_features as already enabled in radio start

Address fix for attiny example sketch

The addresses are reversed when using with the GettingStarted sketch as
described in the comments. This causes the arduino and the tiny to both
be in receiver mode.
