Fully support IJ1's Roi manager functionality

IJ2 has a Roi Manager that does nothing. The IJ1 version of the Roi Manager might not work with IJ2 overlays. Investigate and fix as needed.

Support of existing ROI manager is tricky.

ROI Manager has an empty run() method. It hatches no threads. So LegacyPlugin::run() returns immediately. The manager runs and can affect overlays on shadow ImagePlus. But they never get synced back.

Also OverlayHarmonizer does not maintain mappings between IJ1 Rois & IJ2 Overlays. So any changes to the Rois are lost the next time IJ2 gets ready to call into IJ1 (creating all new IJ1 Rois if needed).

It looks like we either rewrite the Roi Manager in IJ2. Or we take pains to improve the legacy support of ROIs.

If we don't rewrite then a necessary change is to maintain mappings between Rois/Overlays and then keeping them synchronized.

Also without a rewrite another necessary change is to hook some key methods in IJ1 that let IJ2 know that despite being outside LegacyPlugin::run() the legacy layer should harmonize from IJ1 to IJ2.

Moving forward with plan to replace IJ1's Roi Manager with IJ2's Overlay Manager. Initial UI layout committed in d676ad1eb105ccef9f6c0d885e972b3e70d790c5.

Two things to add to overlay manager for compatibility:

Read existing IJ1 roi files and create corresponding IJ2 overlays. See and

IJ1 added More >> List to the ROI Manager in version 1.46q. Support this. (as of 7-2-12 added placeholder code).

Another thing to add to be compatible with IJ1's functionality: in 1.47 Wayne added new functionality: An "Append results" option was added to the ROI Manager's "Multi Measure" command in v1.47c.
