Liquid Research and a Lock out button

[Agema]

I've ignored magic paths for a fair time, so that their research costs are far less than my total research, and grabbed 1 level in 2 paths in one turn with a third path for the spare RPs. It's a little clumsy sorting it out, but it's small enough that personally I wouldn't bother the devs when there's so much else that could be done instead.
