JS/CSS files for deaflip plugin are loaded when not needed.

Currently, the JS/CSS files for dearflip are loaded on pages that do not need them. This is because wp_enqueue_script and wp_enqueue_style are run upon initialization, when they should be run upon shortcode usage. Requesting that a change be made in future versions of dflip and dflip pro that only enqueues scripts and styles when they are actually needed.

I can provide a diff file to the dflip team that makes this change.
