[R] location of Tisean executables when using RTisean and jumping between linux and windows

I have quickly looked into the code. It shows that:

If you have copied your workspace, then you have also copied the object 
.TISEANpath along with your workspace and RTisean looks at first at the 
contents of that object.
So just open the workspace, delete the object and save the workspace again.

Then you will be asked.

Otherwise, RTisean will look for the file .RTiseanSettings in the home 
directory, which is derived on Windows by:
