[Rd] add sessionInfo() option to "save"

Hi All,

I was wondering if there would be any interest in adding an option to the "save" function in R that I think would be useful. I was thinking that it might be useful to have an option that would generate a ".sessionInfo" variable that contains the output of "sessionInfo()", and adds it to the list of objects to be saved. This way, whenever an RData object is loaded, all the information about the R version, and attached packages present would be available for query.

I know I have been bitten by the problem of generating results using different versions of packages and different versions of R. I know that this is partly the idea behind Sweave (and other report generation measures), and perhaps I am at fault for not keeping better track of these types of things, but this seems like it would be useful to a lot of other people besides just me.
