Title: Added support for button images in other languages

Added i18n support for button images.

Users can now specify data-lang (pretty param for data-lc) and get the appropriate button.
Ex: data-lang="es_ES" shows a spanish button.

Added unit tests.

Fixed a bug with app.buttons where buynow was accidentally added resulting in an NaN value.
