[WIN32CSR] Console input simplification:

[WIN32CSR] Console input simplification:
- Put code for processing events for line input in one place, instead of duplicating it everywhere
- Remove "Fake" and "NotChar" fields from ConsoleInput struct. ConioProcessKey didn't actually add Fake events; they were used for the \n when converting \r to \r\n, but this is better done by the line input code.
- Build an input line completely on the server side; this will make it practical to add history and more sophisticated editing later
