Update to version 0.0.14 of the language server

[rcjsuen]

It's been two months since version 0.0.13! There are of course both bug fixes and features but the biggest change is probably the internal refactoring that happened inside the npm module. Assuming everything went fine, you shouldn't be able to notice the difference. :) This release includes the fix for #218.

As always, please use the following Dockerfile to test out the latest changes!
