Subject: [PATCH] Now supports global insert toggle (console CON_INSERT bit).
Removed CRLFs even when K_NOCRLF mode bit is set under some circumstances.
Ctrl-Z (if not handled by inkey) will undo any changes made to the line.
Insert indicator (flashing block) is now placed in (normally unused) cell
1,80 (fixes wrap problem when using insert during input on bottom line of
terminal). Insert mode is no longer automatically turned off at end of
string. Ctrl-Y will now delete the entire line (ala Ctrl-X) if used at EOL.
Optimized Ctrl-Y/X clearing of line for ANSI terminals.
