[Rd] R --vannilla for install/remove/shlib(Re: R 2.8->2.9 change that breaks some upgrade scenarios)

[Hin-Tak Leung]

This is the change I suggested earlier - it should just disable more of user/site customization during package installation/removal, and getting more of R 2.8-like behavior back. Attached and inlined below. 
Against svn r48897 (svn HEAD AFAIK).
