[evolution-patches] Patch for Bug #54659 - Expand/collapse treeview rows on double-click

[Mason Kidd <mason_kidd mrkidd com>]

Hello,
The attached patch fixes bug #54659 (patch is also attached to bug).
This adds the behavior that if you double-click on an expandable row in
the tree view for the mail component, it will expand/collapse that row.
I used the code in Nautilus for this behavior as a guide.

Thanks,
Mason Kidd
