The pages of a menu are now wrapped in an enum that contains either
a builder function or a static CreateMessage. The builder function
is used for the now playing message to always return the currently
playing song instead of mapping a static song. This solves the problem
that the old page is being rendered when the page is recreated because
of being sticky.

Menus can now be created as sticky menus. When new messages appear
in the channel, the sticky message will be resent to be the latest
one in the channel. It only get's recreated every ten seconds max
to avoid getting ratelimited.
To work with recreatable menus, the message handle returned by
the menu is now wrapped into an Arc<RwLock<>>.
