Liquid input overflow incubator and innoculators

[Alexandre Lessard]

This problem is similar to the Issue #79, but it's for the input liquid bar of the incubator.

For example I have 4 incubators, one produce Bacteria and the 3 others consume them. If I open the output of the first when the 3 others are full all my batch will be lost.

The inoculator have the same problem for the bacteria vector input.

P.S. the polymeriser is ok for the polymerising bacteria
