WIP-425 Was getting a 404 when trying to download libcurl4-openssl-dev, ...

...doing an apt-get update fixed it.

Looks like maybe the files got moved or something? I ran `apt-get update` and `apt-get -y install libcurl4-openssl-dev` worked instead of giving me a 404. I did a `vagrant destroy` and then ran `run.bat` again. Server is up and running, now.
