Major Enhancement to web interface, can now pick "All", one or a subset
of samples to compare in a single instance.  Also includes the beginning
of several upgrades to the interface itself, such that data is presented
that is relevant to the organism and collections selected.
Enhancement: On mouseover show project name and sample name, or just
project name.
Bugfix: for waves, don't use "All" keyword, as some projects are flagged
for hiding, whereas others are not, and mixing the two is ambiguous with
that designation.
Bugfix: Enable display in the index for waves, as well as methylation.
