Helpers to reply to messages

[noplanman]

Would be a nice addition to add shortcuts to reply to messages in commands:

This would be especially helpful when there are various conditions when replying to a certain command. Having to set the $data array every time seems overly cumbersome.

Basically this:

$this->replyToChat('My reply text', $data_array_for_any_extras);

vs.

$data = [
    'chat_id' => $this->getMessage()->getChat()->getId(),
    'text'   => 'My reply text',
    // any extras, like keyboard, parse mode, etc.
];
Request::sendMessage($data);

Also:

$this->replyToUser(...); // Which sounds better than `replyToFrom` I guess?

Not sure about other entity types, like replying with a photo or document etc.
