Relative Temperature & Bridging Tower - Adjustable Layer Height Remix

I really liked the concept of a relative temperature tower that supports any material, but I also wanted to be able to change the layer height/nozzle size easily, so I rewrote the layer change G-code to be layer-independent.

;BEFORE_LAYER_CHANGE
G92 E0.0
{if    layer_z > 81+layer_height/2} M104 S{temperature[0] -30} ; Layer 9
{elsif layer_z > 71+layer_height/2} M104 S{temperature[0] -25} ; Layer 8
{elsif layer_z > 61+layer_height/2} M104 S{temperature[0] -20} ; Layer 7
{elsif layer_z > 51+layer_height/2} M104 S{temperature[0] -15} ; Layer 6
{elsif layer_z > 41+layer_height/2} M104 S{temperature[0] -10} ; Layer 5
{elsif layer_z > 31+layer_height/2} M104 S{temperature[0]  -5} ; Layer 4
{elsif layer_z > 21+layer_height/2} M104 S{temperature[0]}     ; Layer 3
{elsif layer_z > 11+layer_height/2} M104 S{temperature[0]  +5} ; Layer 2
{elsif layer_z >  1+layer_height/2} M104 S{temperature[0] +10} ; Layer 1
{endif}
