Title: update :active state of buttons

## Resolves
* Isssue https://github.com/fabien-d/alertify.js/issues/7

Having the `:active` state of the button move the button down by 1 pixel `top: 1px;` also moves the click area down by 1 pixel.

Updated the `:active` state to set an inset shadow on the button.
