Support for load SVG files directly as files.

[mitogh]

For example instead of loading a partial it should be something like:

<?php Load::icons( 'email' ); ?>

// points to icons/email.php or icons/email.svg

Where email is something like:

<svg width="51px" height="38px" viewBox="0 0 51 38" version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
