When opening an image in the tag browser, the loaded collection should be all the images with the selected tag instead of just the containing directory

Currently, when you select a particular image for a tag in the browser, and click the thumb, it opens that image as if you had selected it from the system file chooser. This brings every image in that directory into the collection, regardless of whether they have that tag, and doesn't include any images in other directories that do have the tag.

It seems like a pretty straight-forward change to make it load the image as if it were a search result for exactly and only that tag, and would bring the tag browser behavior in line with the search results dialog.

P.S. Enable double clicking on a tag in the browser to quickly load all images into a new collection.
