0,8ED: Automatic case-folding of commands

 * when enabled, it will automatically upper-case all
   one or two letter commands (which are case insensitive).
 * also affects the up-carret control commands, so they when inserted
   they look more like real control commands.
 * specifically does not affect case-insensitive Q-Register specifications
 * the result are command lines that are better readable and conform
   to the coding style used in SciTECO's standard library.
   This eases reusing command lines as well.
 * Consequently, string-building and pattern match characters should
   be case-folded as well, but they aren't currently since
   State::process_edit_cmd() does not have sufficient insight
   into the MicroStateMachines. Also, it could not be delegated
   to the MicroStateMachines.
   Perhaps they should be abandoned in favour of embeddedable
   regular state machines; or regular state machines with a stack
   of return states?
