PreviewRename prompt

[retailcoder]

Before a rename operation is executed, its impacts are assessed, and the user gets an opportunity to [p]review and skip individual diffs if needed:

The number of locations and modules affected could theoretically reflect the checked items - the OK button should be disabled if none are selected (operation would be no-op).

This is purely client-side functionality: the preview diff literally consists of document edits to be performed.

I like the mockup, but I would want to expose more context lines for the diff, possibly user-configurable, but default more than 2 and less than 5, just to ensure that the user can actually understand what the heck is happening.
