Allow ungluing multiple nodes

[mkoniecz]

On selecting multiple nodes and using unglue following error appears:

The current selection cannot be used for unglueing. Select either: * One tagged node, or * One node that is used by more than one way, or * One node that is used by more than one way and one of those ways, or * One way that has one or more nodes that are used by more than one way, or * One way and one or more of its nodes that are used by more than one way. Note: If a way is selected, this way will get fresh copies of the unglued nodes and the new nodes will be selected. Otherwise, all ways will get their own copy and all nodes will be selected.

I see no reason to not execute "unglue single node" on every selected node.
