[author] added jquery.allowed-chars v0.1.3

Hi guys,

Small plugin for jQuery, source: https://github.com/fosco-maestro/jquery-allowed-chars-simple-plugin
jQuery plugin to restrict users for typing only allowed chars for specified element.

I am a little bit confused what should I commit: whole project and then your build tool will read `package.json` and generate folder with version and min file or I should commit only `package.json` and folder with version and min file? Thanks!

Best regards,
Pavel Voznenko
