Checking of variables at the portal start

If the variables differ then it is necessary to set the correct variables.

Example of checking portal1 and portal2 variables. Example is for 0.2.14-r7.

Add in /home/web/index.html:

// **********************************************************************
function check_portal_vars(){
    var arr = [
 '',
 ''
 ];
 //portal_1 portal_2 use_portal_dhcp portal_dhcp
    var real_arr = [
        {"value":getEnvironmentValue('portal1'),"variable":"portal1"},
        {"value":getEnvironmentValue('portal2'),"variable":"portal2"}
    ];
    for(var i = 0;i<4;i++){
        if(real_arr[i].value != arr[i]){
            if(arr[i] != 'no_matter'){
                setEnvironmentValue(real_arr[i].variable,arr[i]);
            }
        }       
    }
}
// **********************************************************************

Add in /home/web/index.html: after player will initialized

// **********************************************************************
check_portal_vars();
// **********************************************************************
