v2.0.0-beta.2

Major Changes

• 238470c Thanks @Psvensso! - Breaking. The "batch" edit mode is now "draft", reworked: a held draft
  renders its value through the column's own cell renderer (in cellConfirm
  too), an entered new row stays in the grid as a value row until Save all, and
  the edit lane becomes the change indicator and per-row revert - a state icon
  (new/edited/deleted) beside Revert, Restore or remove. Nothing reaches a
  callback before edit.submitAll(): the lane's per-row save and
  Delete-to-clear no longer commit under draft mode.

  Before	After
  editing.mode: "batch"	editing.mode: "draft"
  editing.onCommitBatch	editing.onCommitDrafts
  TMDataGridEditCommitBatchArgs	TMDataGridEditCommitDraftsArgs
  edit.state.newRows[] { tempId }	{ tempId, confirmed }

  New: editing.newRowsSticky (entered rows scroll by default), row
  data-dirty, entry-row data-new / data-confirmed, parts row-state /
  revert-row, edit.state.rows[id].values, labels revertRow /
  rowStateNew / rowStateEdited / rowStateDeleted, --dg-row-new-bg.
  The edit lane now appears under draft mode without onCommitDrafts.

  Fixed: Restore on a deletion-marked row was unclickable in real browsers
  (pointer-events).
