Locating images for import - find in tree style search

[uimage-x]

In a folder with many images, Finn found it difficult to find the ones he wanted to import. For him, selection of images for import could be improved by the ability to perform a Find in Tree type search for a specific character string.

This would automatically select all images it found, so they could be added to the import queue en masse. (Any that were then found not to be wanted could be manually removed from the import list)

In general need a better way to use the file chooser.. suggest search filter for example.
