cleaned up usage of the escape control character: introduced CTL_KEY_ESC and CTL_KEY_ESC_STR
* the reason for the CTL_KEY() macro is to get the control character
resulting from a CTRL+Key press -- at least this is how SciTECO
presents these key presses.
It is also a macro and may be resolved to a constant expression,
so it can be used in switch-case statements.
Sometimes it is clearer to use standard C escape sequences (like '\t').
* CTL_KEY('[') for escape is hard to read, so I always used '\x1B' which
is even more cryptic.
