[QOL] Remplace mode improvement

Some Quality Of Life suggestions for the remplace mode:
* Keep items on belts, do not move them in player inventory.
* Same for stack inserter convertion into normal or fast inserter, I suggest to keep the stack on the inserter, even if the inserter cannot take more than one item in normal conditions.
* Do not extend selection bounds with selected devices, especially for vertical conveyors.
* For mass remplacement, only remplace same alternative as the one selected first: if I select a normal inserter, i didn't want to replace fast and stacks inserters in the same move. Conveyor belts variants (vertical, horizontal and hub) must keep to be replaced together, but not alternatives ones (normal, MK1 and MK2).
