by md_5#2723: Improved Send Command
Previously sending player(s) would always tell the command sender that
they were successfully summoned even if they were not. This change
checks the result of the callback to determine how many players were
sent based on which result (SUCCESS,EVENT_CANCEL,etc) and lists the
count for each type. Additionally a hoverable delimited list of player
names is shown for each result type message component in the chat.
