 * switchText
 *
 * The switchText function is a funtion is called when the user
 * clicks on resume editing (or submits the form).  It calls the
 * php function to switchText and uncomments the html and replaces
 * breaks and everything.  Here all the breaks that the user has
 * typed are replaced with %u2026.  Firefox does this goofy thing
 * where it cleans up the display of your html, which adds in \n's
 * where you don't want them.  So I replace the user-entered returns
 * with something unique so that I can rip out all the breaks that
 * the browser might add and we don't want.
