Set behavior for overwriting text when accepting from a listbox

When you accept from an enhanced listbox immediately before, or in the middle of, a symbol, Visual Assist replaces the text to the right of the caret unless that text is itself a known symbol.  To change this behaviour, edit the registry setting:

HKCU\Software\Whole Tomato\Visual Assist X\<IDE spec>\CompletionOverwriteBehavior

0 = default behavior: VA will overwrite text unless it is a known symbol
1 = never overwrite text
2 = always overwrite text

Close all instances of the IDE before editing the registry to ensure your changes are not overwritten at IDE exit.
