* 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
* [s] in changes by [m] in effort
* pretty painful to do and we now have to set width of columns explicitly - though this will be useful going forward if we allow adjustable width columns.
* even support different width scrollbars in different browsers (have not tested in IE though!)
* remaining bug is that we have an overhang in header when no scrollbar for body (probably not that hard to fix ...)
