a lot of the dev files can and should probably be removed afterwards to keep the image size down

users can install libtcl8.5 & libtk8.5 downstream if packages need these (or the dev versions thereof)

Add GROUPID and UMASK options to RStudio image

Appears that R reads only Rprofile.site but not an Rprofile file in
R_HOME/etc.  However, R installation creates a Renviron in R_HOME/etc,
not an Renviron.site.  It appears also that RStudio copies these into
/etc/R, and renames both with the .site suffix.  If they do not exist,
or /etc/R does not exist, it does not end up reading Renviron at all.
Pretty confusing to me...
