[R] Reading an Rconsole file

[Duncan Murdoch]

I've just committed some code to R-devel (currently the "alpha" version 
of 2.3.0) to allow users in the Windows Rgui to load settings from an 
Rconsole file while R is running.  Currently this is done through the 
Edit|GUI preferences dialog (there's now a "Load" button); if I have 
time I'll also add a loadRconsole() function.

This is intended to be used to switch between different Rconsole 
settings, e.g. large fonts for a presentation versus regular fonts for 
single-user purposes.  Currently it can be done through environment 
variables, but those are sometimes hard to manage; this should be simpler.

As we're now in the alpha phase coming up to the 2.3.0 release, I'd 
really appreciate it if users would test this (and all other new 
features; see the NEWS and CHANGES files).  The alpha releases are being 
built daily and are available on CRAN.  This feature should show up in 
the Mar 29 build.
