Fails Silently when julia is not present in path

[oxinabox]

Excellent Idea. I am looking forward to getting this working.

However, when I simply installed it,
I run Neomake, on a clearly flawed file and nothing happens.

This is because on my system julia is not in the path.
(In the path is something like julia-master and julia-0.4 which are then aliased to julia.)

The issue is not that I broke it by not having julia setup the way it expects.
The issue is there was nothing to tell me it was broken.
To work out why it wasn't working,
I ended up changing changing this line
to redirect not to /dev/null but to jlintserver.out, and then I could see:

cat jlintserver.out
>/bin/bash: julia: command not found

I think the fix is to check the error code when the plugin attempts to start the lintserver.
And if it errors then tell the user.

(Even after fixing that, I still have not got working. It doesn't seem like lintserver is ever being read, or having anything more than the filename written to it. but I am not sure.)
