XL2; Fix Two Speed operation on XL244CL Standard Die
XL200

This change actually impacts all software models due to a design change in how the software determines if it is safe to move material and at what speed.

A poorly documented design choice was making it very difficult get the Two Speed operation on the XL244CL Standard Die to work properly when combined with a two speed Open Loop stopping press.

A global variable that appears to have been added for the closed loop Delay After Shear operation was being used in an attempt to remember what speed to return to after the delay. Otherwise, all presses had the ability to vote on what speed to move at and they all have to agree on the fastest speed, Fast, Slow or Stopped. The Run code was trying to pretend to be the Shear press using the global variable.

This has been modified to give the Run code its own equal vote in what speed the material is able to move at so that it is more clear, separated and no longer prone to race conditions associated with the use of the global variable.
