Long polling! File downloading!

You can now use long polling (getUpdates) by simply creating a function which accepts an update, and starting polling with handle_updates:

function dumper($update){
    var_dump($update); //do whatever you want in here
}
$bot->handle_updates('dumper'); //blocks forever

See the function docs for parameter details.

You can download files by passing a file_id to downloadFile, and it will do one of 3 things, depending on the type of the destination:

• null, omitted:
  content is returned directly
• string:
  content is output into the given string, as a path
• resource:
  content is written with fwrite

Note that this has not been extensively tested.
