Twig2

[DerManoMann]

Summary

• require PHP7
• follow Twig 2.x changes
• update composer deps to new stable versions
• update Makefile (plovr url)
• add more PHP tests
• rebuild twig.js and twig.dev.js

I've set the composer alias to 2.0.x-dev as this is a major update. Not sure if this should go onto a 2.0 branch first and leave master for twig 1.x compatibility for now. Not sure how much more work is going into Twif 1.x...

Failing tests are related to the changed prefix for macros in Twig, ie:
