Fixed \n problem for Oscillations.

WaitSubjectReady() and ShowStatus() used different mechanisms to
present picture and text to the subject. I had to apply the changes to
ShowStatus() as well.
Change delay sequence for each block of discrete.
Movement direction and range filenames.

Changed the syntax in the .bat files to make it less likely that
vertical discrete movements will be made using a range defined for
horizontal movements, and vice versa.
Fixed bug in reading of sequences.
