Screen designer: one label get the settings of the previous one upon selection change

[samuelventura]

To reproduce:

• Create a couple frames or labels
• Select one and change one of its properties
• Click in the second one without clicking some were else before
• The second one should get the same property change

[samuelventura]

The solution was to delay the selection that happened on the onclick event to avoid the selected control to change before the blur of the editing input fired. The delay was implemented with a setTimeout.

The blur handler is part of the new validation model implemented in check.js that allowed to restore a previous or default valid value to the input if the focus is lost in an invalid state. This allows also to safely type temprary/transitional invalid values which makes editing more less cumbersome.
