Switch to php7.0

[djdefi]

Switched to debian:sid so we can get onto php 7 ⚡

Closes #38

[jbrooksuk]

This was merged, but we're still using PHP 5?

@jbrooksuk I reverted this due to lack of ubuntu or debian official PHP7 package, and no APCu module in php7

Happy to revisit this but it was not working well at the time.

The official packages normally lag behind by about 2 years with fixes anyways. :) Also, APC is available now I think.

Could be, it was a lot of piping curl's to bash and ugly tutorials to get it even installed in Debian Sid. I was not ever able to get Cachet to come back after a restart (may have been something else that has been fixed recently)

What distro and php7 install guides are you guys using for development? We can try to reproduce that in our Dockerfile.

I use Laravel Homestead :)

Looks like that is going to take some reverse engineering, as they are using a customized Vagrant box and provisioning scripts.
