git-gui: Support resolving conflicts via the diff context menu.
If the file has merge conflicts, show a special version of the diff context menu, which includes conflict resolution commands instead of Stage Hunk/Line. This patch only supports resolving by discarding all sides except one. Discarding is the only way to resolve conflicts involving symlinks and/or deletion, excluding manual editing.
