Support browsers that don't support SVG

I have old Android phone with default browser that don't support svg and icons are not visible. It would be nice if baguetteBox check if svg is supported before using it.

Hi, I've already got a fallback for SVG support:

The reason you don't see any buttons is because they are hidden on mobile devices by default. You may want to use { buttons: true } option to enabled them.

It work for prev/next but close is not visible. Visible is only background.

Ok, interesting, but I've got a clue, it may be caused by not closing the entity value here:
https://github.com/feimosi/baguetteBox.js/blob/dev/src/baguetteBox.js#L281
Can you change that line to:
closeButton.innerHTML = supports.svg ? closeX : '×';
and test it on your device?

Yes it work.
