Christoph Oelckers 669b13ab8a - cleanup and fixes in console code
* consolidated C_MidPrint and C_MidPrintBold.
* removed some unused code from the console buffer.
* handle console output of centered messages to ensure they get written to the log file and to stdout.
* replaced the non-standard bar strings with simple '-'s. These were making things needlessly complicated when redirecting console output and the new font does not have the characters anyway.
* removed some old code from a time when during console drawing new network events could come and have more text printed. This can not happen anymore with how 2D elements are being handled now so all this code was redundant.
