The problem with pure HTTP is that you can not support pushes from the
server to the client. You'd need at least use eg websockets to get that
working.

As I stated there are at least 2 methods in LanguageService who'll
respond not immediately:
* syntaxDiag
* semanticDiag

So the call to "geterr" returns no result (=void) but you get that
asynchronously and I think you can not support that with plain HTTP.

Please note: I'm not against Tern but if you use LanguageService you
need to keep the above in mind.
