Release candidate version. The pointer in GAS Pressure display is changed to a triangle.

Dependencies:   UniGraphic mbed vt100

Please note, at 2-Mar-2018 the current version of mbed-lib has a defect in Ticker.
https://os.mbed.com/forum/bugs-suggestions/topic/29287/

So, mbed lib version 157 is intentionally being used.
Please do not update mbed library until the problem in the above URL is fixed.
