More folding actions

[netmackan]

One thing I noticed when demonstrating a mind map was that there could be useful to be able to expand all children of one node. Currently one can "Unfold All" but that expands all nodes in the whole map not just under the selected/clicked on one.

Maybe when clicking on one node all of this actions could be available:

• Unfold This / Fold This: Would be the same as clicking on (+) or (-)
• Unfold All Children: Would unfold all nodes under the selected one (or even all selected nodes' children)
• Fold All Children: Would fold all nodes under the selected one (or even all selected nodes' children)
• Unfold All: As before
• Fold All: As before

I have added two more keyboard shortcuts Topic fold all and Topic unfold all to fold/unfold all children of selected topics, so that now - and + by default fold and unfold only selected topics and with pressed alt they fold and unfold whole subtree
