Run OhMyREPL keybindings in a fixed world age

[c42f]

Hopefully this should avoid most invalidations caused by loading other packages as discussed in https://github.com/JuliaLang/JuliaSyntax.jl/issues/252.

Also refactor/replace the NEW_KEYBINDINGS global as it's hard to follow where this is added to, and surface a bunch of other uses of global variables like Base.active_repl up to the top level init.

I'm not sure whether there's some additional wrapping which is needed around the pirating in refresh_lines.jl, etc?

Seems to fix #316 ?

@jakobnissen You've used OhMyREPL a lot more than me, perhaps you could give this a test drive? I'm not entirely sure of all the ways I should be trying to test this.

This PR indeed removes all (noticable) latency even when running with JuliaSyntax 0.3.4 (before Kristoffer's recent type-stability improvements to JuliaSyntax) and importing ProgressLogging.

When using the latest JuliaSyntax, loading ProgressLogging still leads to 277 invalidations before your PR, and 253 with your PR. In either case, latency is not noticable even when the invalidated code is in the REPL - maybe I just can't figure out how to trigger the invalidated code to recompile.

Still, from a latency viewport this is a minor win. If there a no/few downsides, it looks good. If there are any downsides to running in a fixed world age, perhaps a better solution might be to make REPL.jl more type stable.

Right. This doesn't prevent invalidations in the latest world. But running the key bindings in an older world avoids the compiler having to do work to deal with them. So latency should be much improved.

Good to go?

I've updated this to also fix the world age of the pirated LineEdit.refresh_line, and to precompile the implementations of all pirated methods. This should reduce latency a little.

Oh I didn't see your comment. Yes, I think it's good to go now :-)
