Dev: Sync to 5e444c7e09126c87965e69873fc5152fd097014b - the build script
was having a few sync issues
New: cache() methods for rows and cells.

- I'd previously added columns().cache() which gets the cached
  information about filtering or sorting, but this rounds the API off,
  extending that also to rows and cells:

  - rows().cache()
  - row().cache()
  - cells().cache()
  - cell().cache()
