* rewrite of the win32 dedicated console:

Browse source 
1) NET_Sleep() no longer watches for input, Sys_Sleep() added for waiting
     on input.
  2) Added "CtrlHandler" for trapping Ctrl-C and other quit methods not
     handled by signals on windows
  3) Added history support
  4) Added tab completion
  5) Removed automatic cursor/scroll adjustment (too problematic)
  6) Enable mousewheel scrolling
  7) Stop using the InputBuffer for editing

  This seems to work pretty well now, but I jumped the gun on a previous
  commit message by saying you can scroll now without locking up your server.
  That was only true up until the point that a server tried to print to
  the console, at that point it will hang until you release the scroll bar :(
  It may be possible to get around this by using a seperate thread for
  console output, but that's a whole new can of worms.

==================
CON_CtrlHandler
The Windows Console doesn't use signals for terminating the application
with Ctrl-C, logging off, window closing, etc. Instead it uses a special
handler routine. Fortunately, the values for Ctrl signals don't seem to
overlap with true signal codes that Windows provides, so calling
Sys_SigHandler() with those numbers should be safe for generating unique
shutdown messages.
