console-client: Cleanup the escape code

This change fixes a bug where multiple tildes were sent if a user typed
\r~~ This is unlike ssh, which allows nesting of escape sequences by
ensuring that only the second tilde is sent after the command sequence
is issued. This patch fixes the behavior so the console-server only ever
gets \r~ for an issued \r~~

This also prepares the escape sequence handling code for an upcoming
change which allows a user configurable escape sequence in addition to
the default ssh like one.
