autonumeric 4.9.0

on Node.js NPM

• Closes #728 Unable to group by 2 using digital group spacing options

Changes:

• This version modifies the AutoNumeric.options.digitalGroupSpacing.two option, which is now named AutoNumeric.options.digitalGroupSpacing.twoThree
• The AutoNumeric.options.digitalGroupSpacing.two now effectively groups only by 2 (and not by 2 and 3 like before for India's numbering system)
