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.
