Implemented ability to upload .rda file in epiview.R .

Deleted commented lines writing to graphics devices (files)
in epiview.R which are long redundant.

Other code and presentation polishing.

We still have the bug that the Y-chromosome on its own will not
display (error). In fact, display without error requires at least
one autosome, then everything works fine. I have traced this problem
to a line in RCircos and will lodge a separate bug report.
