Pls support node 6 LTS version

[JimmyLv]

It seems that flipchain is a dependency which only support node7, but node6 is the LTS version that is most of choice.

error flipchain@0.4.4: The engine "node" is incompatible with this module. Expected version ">= 7.7.2".

After I chose install with --ignore-engines but still blocked by:

⠄ fliplog: EBUSY: resource busy or locked, rmdir 'xx-react-scripts\node_modules\d-l-l\node_modules\fliplog'

updated uses chain-able when I push
