Crash when Y-values of cursor exceed buffer

[sorrell]

When the BufferHeight is filled with text (text goes to bottom of console), and we utilize "Shift/Alt + Enter" to go to a newline, the program crashes because of

Unhandled Exception:
System.ArgumentOutOfRangeException: Value must be positive and below the buffer height.

I've worked around this by clearing the console and setting the CursorTop to 0.
