Revise Idle-Settings format, add pictures (#293)

* Revise Idle-Settings format, add pictures

Changed the formatting of settings and values to match the rest of the wiki, added pictures.

* Update Idle-Settings.md

Corrected case of referenced image. Didn't see it on the local build, but perhaps strict casing when running PR checks?

* Update Idle-Settings.md

Scout's honor, I ran build again locally. Updated the other images which had case disparities.

 The closed loop idle air strategy can utilize all three terms (Proportional, Integral, Derivative) to provide accurate control of the IACV or ETB position and achieve a stable target idle. The 3 terms are calculated, added up and then limited by the _Min_ or _Max_ values to arrive at the final _Idle: Closed Loop_ output. The error (difference between the _Idle Target RPM_ and actual RPM) is written on the variable _idleStatus_Error_.

 The _open loop base position_ value is multiplied by the value in this table. For example, if the _open loop base position_ value was 30% and the multiplier was 1.50 at 0 degC, the commanded base position at 0 degC would be 45%. A multiplier of 1 would simply output the open loop base position value.
