`abs` is deprecated for floats, use `fabs` instead

[DarkMatterMatt]

In line 496, return( abs( sMotors[ index ].current) ); it gives the warning *Warning*:Symbol 'abs' is 'deprecated' definition. There may be alternate symbol with equivalent functionality.

Quoting yourself,

we deprecated 'abs' for use with floating point numbers, the preferred replacement is 'fabs'

sMotors[ index ].current is a float, if I change abs to fabs the warning goes away.
