[Rd] Windows problem related to using shortPathName for Sweave style file

A follow up on the actions taken.

1) In R >= 2.7.0 whether Sweave() inserts


is controlled by the environment variable SWEAVE_STYLEPATH_DEFAULT which 
sets the default for RweaveLatex's 'stylepath' argument.  So setting 
SWEAVE_STYLEPATH_DEFAULT=FALSE inserts just \usepackage{Sweave}

To work with this, when tools::texi2dvi finds it is being used with 
MiKTeX's texi2dvi, it makes use of the -I argument of the latter to put 
the path to Sweave.sty into the input path.

This means that users of MiKTeX will want to set 
SWEAVE_STYLEPATH_DEFAULT=FALSE in their environent, e.g. in .Renviron.

2) For 2.8.0, it is planned that the default for 'stylepath' will become 
FALSE.  In that version tools::texi2dvi will set the appropriate input 
path on all platforms.
