[Plugin: Ambrosite Next/Previous Post Link Plus] Add a "classes" argument to [previous/nex

Hi Ambrosite and thanks for this plugin I always install on all my new wp works.
I’m using a css/html framework on my current wp project, that lets me add cool tooltips just using classes, so I’ve modified your plugin adding a “classes” argument to [previous/next]_post_link_plus functions.

I think it might be a useful feature, so I hope you will add it in a future release.
