[#94,transform][m]: rework transform functionality and integration extensively (+ its working again!).

* view.transform.js: major refactor
  * general record transform rather than column transform
  * Normal dataset view rather than modal
  * Reworked UI
  * split out css from grid.css and simplify
* model.js + backend.memory.js: transform implemented on Dataset and Memory (Dataset passes off to _store).
* multiview: use new transform view
* _includes/recline-deps - rework to use source files rather than built ones

src/model.js
