Fix 608

[nathandunn]

fixes #608

Control edits:

do a UI review

• [x] test gene set editor behavior:
  • [x] can only add once
  • [x] remove does not seem to work
• [x] review "fetch new gene set" versus, let's use a gene set builder

gene set editor feedback

• [x] Different -> Differential
• [x] remove reload visible, new geneset, edit geneset, reset, edit gene set (in visible)
• [x] move Remove down
• [x] remove controls about edit / remove
• [x] play with most differential in the sorting box

---

• [x] add gene set editor button back to solve the use-case: I want to see a set of pathways with certain names or genes
• [x] other Jing feedback

---

• [x] fix state issue in XGSA render() method . . multiple state AND variable?
• [x] sorting should be saved when going back and forth:
  • [x] limits
  • [x] diff sort
• [x] sorting should be absolute diff (to pull) and then cohort diff (to view) -> same for CNV + Mutation, but the background is always the same
• [x] remove number limits
• [x] remove geneSetSortBy? from XGSA?
• [x] add "find gene" to gene set filter (separate entry)

---

• [x] add number limit and "most similar" vs "most differential" to visible controls
• [x] remove "Find Gene"
• [x] enable number limit in main view:
  • [x] add 'update' button
• [x] enable most similar vs most differential in main view: -> map geneSetSortBy to: sortViewBy and sortViewOrder

---

IMPORTANT:

Unsure:

• [x] provide a view for "most similar" or "must different" ??
• [x] remove gene set editor link and popup??
