Fixes memory leak caused by J2DTextBox_SetString()

Browse source 
Setting the string on each frame fills up unallocated memory and causes
a hardlock.

Instead, call J2DTextBox_SetString() on stage load (since the memory is
freed level transition) and modify the already set string directly on
each frame.
