No delete confirmation (and fix)

[adiakeka]

There's no delete confirmation. To add one, change code line 310-312 from

$.post("",{'do':'delete',file:$(this).attr('data-file'),xsrf:XSRF},function(response){
	list();
},'json');

into this

if(confirm('Are you sure?')){
$.post("",{'do':'delete',file:$(this).attr('data-file'),xsrf:XSRF},function(response){
	list();
},'json');
}
