Right aligned token input.

[RutujaKhandpekar]

Token input is made right aligned by adding one more option in DEFAULT_SETTINGS. This can be useful when using locale variables for choosing language e.g. languages like Arabic are right aligned. Therefore in this case by providing one option 'rightAligned : true' it can be made right aligned.

I am providing this jsfiddle link for a test : http://jsfiddle.net/Rutuja_Khandpekar/qbud0vgb/1/

Here by default I have given a option 'rightAligned: true' in DEFAULT_SETTINGS. By changing it to false, again it will be into original form i.e. left aligned.
