Research filtering on required item

[Boogieman14]

When I'm working on setting up my blue research production chain, I frequently find myself clicking through all available techs to find one that doesn't need blue packs. I think it might be a useful addition to be able to filter the research by required items, so I can see this more easily. Just enable the filter and it immediately shows me all the red/green required researched. Depending on the direction research is going, this could potentially still be very useful with any other items that come in place of the science packs.

We also sort the technologies by the highest science pack needed

It's not an actual filter, but this was mentioned in FFF159, so there's hope.
