git-cvsimport: allow author-specific timezones

Browse Source 
CVS patchsets are imported with timestamps having an offset of +0000
(UTC).  The cvs-authors file is already used to translate the CVS
username to full name and email in the corresponding commit.  Extend
this file to support an optional timezone for calculating a user-
specific timestamp offset.
