"Other" Properties table is not working

[Jorge Pérez]

When we want to add a new property inside "Other properties" tab (of a network or a node) the button is not responding.

Completed class PrefixedOtherPropertiesTablePanel (gui/dialog/common). Made small changes in some other classes (Node, ProbNet, dialogs, etc.). Changed objects of class HashMap to LinkedHashMap in multiple classes in order to be able to control the order of the additional properties.
