PHP7 port

[halfa]

Should be tested against composer requirements.

Tested today under debian/jessie:

sudo apt-get update && apt-get install php7.0 php7.0-curl php7.0-xml

This will replace the current php5 engine by php7.
We got full support for Symfony 2.8 hence we stick to it as 3.0 is not an LTS.

Here are the changes to the composer requirement:

The doctrine/annotations update is mandatory, see this thread

Apparently no issue, but I cannot say if perfomance-wise this is interesting to push in prod.

Should be safe, as there won't be any critical production event until November :-)
