@nightwing @andrewnester 👋 from github/linguist, the library responsible for language detection on github.com, and other places.

This PR has come to my attention as one of our tests has started failing because of this change. GitHub no longer uses the Ace editor (it hasn't for quite some time) however we maintain a check against Ace modes for all languages added for third-party users of the gem that may still be using Ace.

A change on our side is easy enough to implement (change the path), but I'm curious to know what the rationale is for this change as it's not explained in the OP and there's no referencing issue.

Also, were https://github.com/ajaxorg/ace/blob/master/lib/ace/mode/jsoniq.js and https://github.com/ajaxorg/ace/blob/master/lib/ace/mode/xquery.js deliberately left in lib/ace/mode and not moved to src/mode?

Having these two files in the old location makes our change a little more complicated as we now need to query two locations. I'm also trying to judge if things are likely to change again within the near future.

HI @lildude ! Thanks for reaching out!
The idea of the change comes from the fact that we want to publish a source code of Ace as an NPM package. To make it developer friendly we decided to switch to Common JS first so hence this change.

The mentioned modes are deliberately left in the lib folders :)
