Running on PHP7

[simonszu]

I have successfully built a docker image for tweetnest, running on the official php image, which, obviously, uses PHP7. I have noticed some errors/warnings during the installation process which mention some faults, and that future PHP versions would recognize these faults as an error.

So my question is: Is tweetnest generally ready for php7? There isn't lots of maintenance going on here, and maybe i should re-build the image for php5? Explicit side note to @alexanderadam, you are, besides myself the only other user who uses this image. Did you notice these notifications as well? Especially in the timezone drop down, and on the first successful display of setup.php after the installation succeeds.
