[VIM] product name spelling error (CVE-2013-2616 - MiniMagick)

[Christey, Steven M.]

The original disclosure by Larry Cashdollar at http://seclists.org/fulldisclosure/2013/Mar/123 spells the product name as "MiniMagic," and this is reflected in OSVDB:91231, BID:58448, and possibly other sources.  However,  the correct spelling is "MiniMagick" as seen in the vendor URL (https://github.com/minimagick/minimagick).
