Keyboard events handling for search input field

[GoogleCodeExporter]

Input type of type 'search' has special handing in WebKit code, making current 
implementation of sendKeys does not work correctly for this type of input - 
text is not inserted into the field.

As a temporary solution, this special handling was removed by re-implementing 
RenderTextControlSingleLine::createSubtreeIfNeeded() in 
WebCore/platform/hl/RenderTextControlSingleLine.cpp, however less intrusive 
solution is needed.
