Distiller got updated along with the distillation skill. To purify essences
one has to use 'distillation' skill along with the alchemist's workbench.
Distiller no longer requires time to be used when distilling but is now
similar to other workbenchs.
Although time is no longer issue in essence purification, the balance needs to
be restored! Therefore distillation success is based on characters skills and
..stuff..
