Shah Khatri added the KofC_getLanguageLink function on 5/31/06.  Modified it again on 3/4/07 and
  3/8/07, as follows: Added a "goToCurrentSiteHomePage" (boolean) parameter.  If it is true, the new
  link refers to the current site's home page in the new language.  Otherwise, the new link refers to
  kofc.org.
Shah Khatri copied David Gianetti's language-cookie related functions on 6/12/06
Shah Khatri updated the image path in KofC_rotateHomePageImage() on 2/24/07
Shah Khatri removed call to KofC_ChooseCSS() from within this file on 2/25/07
Shah Khatri updated KofC_ChooseCSS() on 2/25/07
