Update Ace library

[Kaosumaru]

Hi, it seems that older version of ace library is bit buggy - it seems to block right alt+[a/z/l] keys (commonly used to input letters extending latin alphabet in some languages). I haven't pinpointed the exact issue, but updating ace to newest version seems to fix it. Since electron branch is in active development now, I'm setting it as target.

I'm using an US International keymapping on mac, and it does indeed some weird things, i didn't even realize 😱

Nice catch and good to know newest version of ace fixes it.

This is a nice fix. Thank you :)

Should this be updated to use ace as a dependency via packages.json?

[blurymind]

right now it is just included with Yarn in the libs folder, I need to refactor the code a little bit so it uses require to include it from node_modules instead. That way we will be able to use npm to update it in the future from https://www.npmjs.com/package/ace-builds .. So for yarn-electron I am gradually moving external dependencies to package.json and removing them from the lib folder, but haven't gotten to ace editor yet. :) In any case pulls to do that are welcome.

This pull just overwrites the one in the libs folder

Ok, lets merge this like it is for now- as it doesnt cause any regressions. We can move it to node_modules in another pull

@desplesda I just merged an update to allow updating ace and its modules via npm https://github.com/InfiniteAmmoInc/Yarn/commit/81b7326659612c403c5f5d50caf7a6d51a739d3f

There are still a few other libraries that need to be migrated, but lets take it slowly with that kind of re-factoring as it needs testing for regressions
