Add a loss of control alert

A movable alert in the middle of the screen for the strongest active effect from C_LossOfControl: icon, cooldown sweep, the effect's name and the seconds left. A school lockout reads "<School> Locked". It opens on LOSS_OF_CONTROL_ADDED / _UPDATE and rescans every 0.1s while shown, because a refreshed debuff or a second kick changes the timer without an event. The labels are Classic Era's LOSS_OF_CONTROL_DISPLAY_* GlobalStrings, added to each locale file. The README lists the alert and the dressing room controls.
