Issue 19 solved

Revert the last Haptic changes (was unfinished, no more spare time during the week-end, sorry!)
Revert my last modification on main views (offset not displayed in Bar Graphs, I was wrong)
PPM Center now configurable for each servo
No mean on the Batt voltage when in the calibration menu to have a faster response when calibrating
SD card Backup / Restore Models feature started
Some french translations fixed
