Made InputBit class able to set its port bit, so it can turn on the pull-up resistor
Fixed some bugs in ADC to get it working with multiple channels
Added ability to DeviceStream to choose whether or not to send CR along with LF character
Changed FixedPoint class to store as a 16 bit integer rather than 2 8 bit integers

This simplifies a lot of things and made it easier to fix bug that numbers with a 0 to
the right of the decimal (e.g.0.01) would fail to print properly.
Fixed a release build issue
Made it possible to set INA219 configuration values without setting calibration values.

I am doing the current calculations directly from the shunt voltage value so no need to set calibration
Added new control commands to TextLCD, to set line
Updated Button class to new Bit class and made it do a repeating timer rather than a one-shot that kept getting fired
