This is important when the user typed text that is a different
case than the completion. This has no affect on the Console, since
it matches completions case-sensitively. This is used in the up-coming
Database Query view for words like "SELECT" and "INSERT".

* page/inspector/TextPrompt.js:
(WebInspector.TextPrompt.prototype.clearAutoComplete): Restore the user typed
text in the original DOM range that complete() saved away.
(WebInspector.TextPrompt.prototype.complete): Store away the fullWordRange
and it's text content so clearAutoComplete can restore it.
