Stitching_Grid: add default BF settings

When running BF.openImagePlus, always ensure the dimension input order
will match the underlying dataset's order, and the output order will be
XYCZT to match the ImageJ constraints.

Also, ensures crop will be false.
Stitching_Grid: add "TilesToRois" checkbox

When this option is selected, all tiles in the stitched image will be
added as Rois to the RoiManager. Each will be labeled with its
appropriate Z,C,T and imageIndex coordinates in the underlying dataset,
as well as the file name on disk that the tile was read from.
