fix: canSendDefaultMessage ignores overwritten events 

This refactors three methods
regarding powerlevels. It
makes them a little bit more
readable and removes
unnecessary checks. it
also changes the canSendDefaultMessage
method in a way that it also
checks the events map in the
powerlevels so that it returns
true if message events are
overwritten there. It also
improves the dart docs and
explains in more detail what it
does.
