Update snipmate's supertab handling for the latest supertab version.

[ervandew]

I made some changes to supertab to deal with users who have mapped / to something else and didn't want supertab clobbering those mappings. So now supertab has a couple <Plug> mappings for forward/backward completion and some code to retain the user's original mappings.

However, snipmate is still relying on / to kick off supertab, so I made a patch to utilize the new <Plug> mappings when available (should retain backwards compatibility with older supertab versions), which resolves any issues I've encountered with supertab + snipmate + user mapped /.

Let me know if you have any questions regarding these changes.

Thanks!

Thanks Marc. It's a shame the primary source is abandoned, but it's good to see you and garbas providing maintained forks.

I forgot to update the BackwardSnippet function as well for the new plug mappings. The latest commit takes care of that.
