Enhancement: Finally killed off showmethylation.py wrapper.
Enhancement: Killing off showchipseq.py, for easier passing of
information.
Enhancement: project dropdown on query_form is now mulitiple selection.
Enhancement: Chipseq project names can be selected on query_form.
Enhancement: start of separation of queries for methylation and chipseq,
so that multiple sets of data can be drawn, overlapping, with less
wasted effort.
Enhancement: Killing off Showchipandmeth, though, the code has not been
integrated.  However, since it wasn't working before, this does not
repair anything yet.
