[companion-integrate] RTI - Removal of SFWvim Package

[Steven M. Christensen]

This is a RTI for the removal of the vim package from the Companion CD. 
  vim is now part of Nevada in a newer version and this package is no 
longer needed.  The webrev is at

http://companion.sunfreeware.com/downloads/vimwebrev/

This has been reviewed and approved by Paul Cunningham.

The cmd/vim, pkgdefs/SFWvim directories have been removed.  Targetdirs, 
cmd/Makefile, and pkgdefs/Makefile edited to remove references to vim.

No other package depends on vim, so this has no affect on nightly builds 
other than to stop creation of the vim package.
