Image Meta Data tab

• images cannot be remove, but in expanded mode, it can.
• selecting image no longer highlight table. the reverse works fine.
• visualize/saga/ImageMetaDataWatcher.js:272 returns -1.
• when a non-meta table is selected, images are shown, but not the toolbar.
• after table is removed, images are still there.

image external api does not mix well with firefly viewer.

• firefly viewer uses 'triViewImages’ viewer_id while api has no viewer_id. as a result, images loaded by api will be lost once table or other searched data are returned.

• catalog overlay are drawn outside of the images.

more issues:

• It's possible to select distance tool and then area selection. First drag would define area selection, all the following line. A click would be defining a 0 length line, even if point selection is enabled. moved to DM-6656
