Using esLint in OCA/pos repository

To avoid to have warnings and errors in Travis log, regarding Javascript lint, you can use the OCA Tools pylint-odoo.

First Time : Install eslint

Run eslint to adapt your code to OCA convention

git clone https://github.com/OCA/pylint-odoo
cd pylint-odoo

eslint --fix --config pylint_odoo/examples/.jslintrc $MY_MODULE_PATH

This command will fix most of the lint error syntax, and list the errors the tools can not fix automatically. You can then fix them manually.
