Make notifications (alerts) customisable

[srustamo]

Clearly some might like stock message alerts in these lines:

./org-pomodoro.el:479:  (org-pomodoro-notify "Pomodoro completed!" "Time for a break.")
./org-pomodoro.el:488:  (org-pomodoro-notify "Pomodoro killed." "One does not simply kill a pomodoro!")
./org-pomodoro.el:501:  (org-pomodoro-notify "Short break finished." "Ready for another pomodoro?")
./org-pomodoro.el:511:  (org-pomodoro-notify "Long break finished." "Ready for another pomodoro?")

For others, please consider making the messages optional, perhaps, customisable.

alert package can only handle an overall style of message from this package, but not individual messages, AFAIK, so tuning the individual messages from there does not seem to be an option.

This is possible through the customization options in alert though.
To customize how all notifications from org-pomodoro are displayed (through minibuffer messages in this case) one would do:

 (add-to-list 'alert-user-configuration '(((:category . "org-pomodoro")) message nil))

To customize a single of the alerts it is for example possible to match on title:

(add-to-list 'alert-user-configuration '(((:title . "Pomodoro completed!")) message nil))
