selecting "suitable container" needs more intelligence handling liquids.

[scrom]

if the suitable container contains a liquid then we need to check if the item we're adding will combine with the contents. If it wont then we need to select a different container.

the inverse is also true. If we're adding a liquid to a container that already contains something (solid or liquid), a different container should be found.

note this also needs to handle powders

note - it's the different container bit that isn't handled yet.

This also needs to support splitting quantities

suitable container handling is much improved now but the fundamental issue described here is still an issue.
