* Add con_log.c to log all console output

Browse source 
* Add con_passive.c to cut down on #ifdef DEDICATED in sys_main.c
* Add Sys_ErrorDialog to report ERR_FATALs to the user
  + On Windows use a MessageBox and offer to copy the console log to the
    clipboard
  + On everything else print to the terminal and save the console log as
    crashlog.txt
