Infinite-Capacity Shifts

Now you can mark a shift as “unlimited capacity” which will replace the Max Simultaneous equipment option. This allows users to repurpose shifts to be something like ‘equipment schedules’, in case you want to only allow the use of certain equipment within a given time window (e.g., only use these machines M-F between 8-5) without otherwise constraining how many machines can be given a time. This is especially useful when the machines attached to the shift have unlimited capacity, themselves since the shift will then not artificially constrain how many operations can go on the machine at once.
