[R-pkgs] pls 2.4-3 released

[Bjørn-Helge Mevik]

Version 2.4-3 of the pls package has been released.  Windows and OSX
binaries should appear shortly.

The pls package implements Partial Least Squares Regression, Principal
Component Regression and Canonical Powered PLS Regression.

The major changes are:

- Can now perform cross-validation in parallel, using the facilities of
  the 'parallel' package.  See ?pls.options and the examples in ?mvr for
  details.  (Note: in order to use MPI, packages 'snow' and 'Rmpi' must
  be installed, because 'parallel' rely on them for MPI parallelisation.)

Other user-visible changes:

- In order to comply with current CRAN submission policies,
  pls.options() no longer stores the modified option list in the global 
  environment.  This has the effect that the options will have to be set
  every time R is started, even if the work space was saved an loaded.
