Implement new ractives

[nachocab]

Ractives coming down the pipeline

• volcano plot (all genes) + jitter plot (single gene) + line plot (all genes)
  • they are all linked (hover, click)
  • 3 colors grey80, black (significant), red (clicked)
  • add a new row of plots, so you can compare with another gene (choose side by side, or top-on-bottom, choose same scales or not, symmetric or not)
  • draggable limits to define cutoffs
  • allow adding manual annotations for specific (subsets of) probes
  • I don't know how hard it would be, but resizable plots would be awesome (a dashed line appears around the plot on hover and the cursor changes to a resize cursor, I think I saw an SVG example of resizing)
• zoomable scatterplot (needs a fix in the axes)
• AA <=> NT
