/*
upgradeSearchOnWebkitBrowsers function makes the search
input boxes in an HTML form appear and behave like 
search fields in Mac OS X applications.
The function first looks if the page contains any forms
then looks for an input field that has the name="search"
attribute. When such input is found, it injects three 
new attributes that make Webkit browsers (such as Safari
and OmniWeb) show the goodie.
JavaScript is used to do this since these particular attributes
are not standard HTML and will break the validation.
All non-Webkit browsers should ignore the attributes
and display the regular input box.
