AP_AnalogSource: make read_average() return a float
...
this allows it to take advantage of better than 1 bit resolution by
averaging

AP_AnalogSource: fixed reporting of VCC
...
the VCC pin number should not be converted

AP_AnalogSource_Arduino: fix to allow analog port to be read to be specified as a "channel" (i.e. A0)
...
Also fixed example range finder sketch to work with interrupt enabled AP_AnalogSource_Arduino class

AnalogSource: make the Arduino AnalogSource interrupt driven
...
this fixes several problems with reading analog sources:
- we were getting poor values because we didn't wait long enough for
an analog source to settle
- we wasted a lot of CPU cycles waiting for conversions
- we were not taking averages over many samples, which we did with
the old AP_ADC driver on the APM1

Arduino 1.0 - changed all #includes of "WProgram.h", "wiring.h" and "WConstants.h to "Arduino.h".
...
Modified FastSerial's write function to return size_t (number of bytes written).

AnalogSource: return a float from read() method
...
this gives the full resolution when using the ADC backend. It also
adds scaling for the Arduino backend

RangeFinder - small bug fix to initialise prescale variable.
...
Fixed up example sketch so it compiles and works again!

purple: Added AnalogSource library
...
this library abstracts out the way of getting an analog value. If the
ADC library is being used then it calls the ADC Ch() method, otherwise
it calls analogRead()
