show diff in "replace with local history" dialog on selection change

[tobiasmelcher]

The "Replace With" -> "Local History ..." option in the source editor context menu launches a dialog that allows users to revert to a previous version. Initially, this dialog displays a list of all available revisions:

Previously, selecting an entry from the revision list did not trigger any action. Users had to double-click to view the differences.

This pull request enhances the behavior by displaying the differences upon a single click/selection.

This pull request changes some projects for the first time in this development cycle.
Therefore the following files need a version increment:

team/bundles/org.eclipse.team.ui/META-INF/MANIFEST.MF

An additional commit containing all the necessary changes was pushed to the top of this PR's branch. To obtain these changes (for example if you want to push more changes) either fetch from your fork or apply the git patch.

Here a lot of nesting is happening.
Can we decrease that by returning null early?

Issue was detected in an internal UX review. UX experts were asking us why the UI is not updated when an entry in the history list is selected. Question is absolutely valid from my point of view.
