New release (3.4b) of the changebar package

[Johannes L. Braams]

Hi all,

I have just prepared a new release of the changebar package to mirrored onto 
CTAN.
The changes are;
- support for VTeX has been added, thanks to a contribution by Michael Vulis
- support for colored changebars has (finally) been added
- a problem with changebar and shadethm used in the same document 
  has been fixed.
- a number of minor typo's have been fixed.

Kind regards,

Johannes Braams
