Title: Bug report + fix: NullPointerException at [...](GuiRefinery.java:85)

Steps to reproduce bug: click a refinery GUI input slot with either a non-LiquidContainer or with nothing.

Note that it would almost certainly be cleaner to just clear the slot instead, but that was getting non-trivial and not something I'd like to edit in a web interface.
