Bad habits
I've updated all the bundles to use the command 'Snippet' instead of 'Snip'. This was causing a conflict with the latex-suite plugin which defined a similar command. The Snip command has always been called Snippet but vim will let you use shortened versions and it'll try its best to match. Obviously latex-suite's Snip takes preference over Snippet and so users would get an E488 error.
Apologies for this if you've encountered this; it was purely me being lazy.
