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.
Merge branch 'stitching-display-tiles'

Adds a checkbox to grid stitching allowing all tiles to be added as Rois to the
RoiManager.

Each Roi is labeled with the identifying series, z, c, t coordinates as well as
slice position in the image.

Also, each label contains the file name associated with that tile.
Stitching: Created RoiPicker tool

This tool is automatically loaded when stitching & "Add tiles as ROIs"
is enabled.

The RoiPicker can be used to select, via clicking on an image directly,
one or more Rois containing the given position in an image. Repeated
clicking cycles through the matching Rois.
Merge branch 'roi_picker'

Created a RoiPicker tool, which allows for manually selecting Rois by clicking
on an image.

Enabled when stitching and "Add tiles as ROIs" is selected.
