Before this commit : The library underscore.js and
underscore.string.js were used in the ODOO solution.
After this commit : Every usages of a function from
underscore.js lib has been replaced with native javascript.
The goal is to remove all usages of underscore.js and to
not use anymore this library in ODOO.
