- changed I_PrintStr so that it doesn't add everything to the RichEdi…

…t control right away.

The RichEdit control can become quite slow with large amounts of text being added constantly.
Since anything that gets added while the game is running can't be seen anyway unless a fatal error is produced, it buffers the text locally now, without any processing, and only adds it to the RichEdit control in case a fatal error causes the control to be displayed again.
