Auto-sweeper moves items from high priority storage to low priority dispenser

Dispensers work like machines, and they always have priority over storage. 

For example, if your lime-storage is prio 8 and the metal refinery is also 5, the sweeper will fill the refinery, regardless the lower prio its set to.

Same with the dispenser. Its not cleary explained though.

It's rather confusing, as the errand type shown in the dispenser is "storing", like storage bins, rather than "supplying" like refineries.

it is really very strange
the duplicant first places the resource in the storage bin, and then moves it from the storage bin to the dispenser

I assume that the problem is due to the absence of one line of code in the class "ObjectDispenserConfig" in the "DoPostConfigureComplete" method

storage.onlyTransferFromLowerPriority = true;

I made a mod that should help fix this problem
