Fixing http_build_query function causing return of & instead of & on some servers when using {MENU: xxxxx} with parameters, thus breaking parameters passing to the menu.
Eg. {MENU: path=news/latestnews&test1=true&test2=false&test3=44}
Will return call the menu with test1=true&test2=false&test3=44 instead of est1=true&test2=false&test3=44
causing only the first parameter key passed, to be valid
