IDE: Optimization of modification events processing in text editors.
Too many modifications types where registered, and then too many events were fired.
Also, in case of uninterrupted sequence of events, updates to the model is deferred to the end of that sequence (wx.Callafter).

ListSwitch widget displays one item of an HMI:List depending on value of
given variable. Main element of the widget must be a clone of the list or
of an item of that list.
Given variable's current value is compared to list items
label. For exemple if given variable type
is HMI_INT and value is 1, then item with label '1' will be displayed.
If matching variable of type HMI_STRING, then no quotes are needed.
For exemple, 'hello' match HMI_STRING 'hello'.
