More conversions to the new design.

Removed run arguments.

Converted run arguments to pipes.

Removed a deprecated run argument.

Changed the location of the temporary directory creation command.

This change now avoids relax from crashing on Windows when the directory does not exist and follows
a post by Ed at: https://mail.gna.org/public/relax-devel/2008-07/msg00047.html (message ID:
7f080ed10807291455k1d11d51fpdb2382806e55efdb@...).

Note that the directory separators are fine in Windows using the current syntax ('/').

Also, note that this change is temporary as the temporary directory should be placed in an user
accessible location and created as proposed by Ed in a post at:
https://mail.gna.org/public/relax-devel/2008-07/msg00048.html (message ID:
7f080ed10807291507x5b6aab2fv820a6fc219fc7e2b@...).

Added the ability to handle missing RDCs.

Improved the tearDown() function so the temporary directory is deleted after the test.

This follows r7026 (http://svn.gna.org/viewcvs/relax?rev=7026&view=rev) and the proposal of Edward
d'Auvergne at: https://mail.gna.org/public/relax-devel/2008-07/msg00038.html (message ID:
7f080ed10807290219m18601df6nf2df7e91848a9680@...).

Added the setUp() and tearDown() functions to the palmer system test code.

A temporary directory is now created for ModelFree4 output.

This directory is only created and the function for deleting it still needs to be added.

This follows the proposal of Edward d'Auvergne at:
https://mail.gna.org/public/relax-devel/2008-07/msg00038.html (message ID:
7f080ed10807290219m18601df6nf2df7e91848a9680@...).

Uncommented a line as this was a temporary and local change which should not have been committed.
