La Suno / Mbed 2 deprecated afero_poc15_180302

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.

In this version, format of GAS Pressure Display has been changed.
