Release 17 tends to hang on powerbox-http-proxy setup

[ocdtrekkie]

I am unsure what causes this, but it seems to happen for upgrades or sometimes on the second/additional launch of a grain that has previously worked correctly.

I'm guessing the proxy never creates the root cert, because it can't find the environment variable.

continue.sh is the related script here: https://github.com/sandstormports/wordpress-sandstorm/blob/master/continue.sh but the environment variable is set in the pkgdef, here: https://github.com/sandstormports/wordpress-sandstorm/blob/master/.sandstorm/sandstorm-pkgdef.capnp

You probably need to set the same variables in the definition of continueCommand, below.

...Wow. You know, I had no clue that there were two separate sets of environments there... I feel dumb. I'll fix it. :|
