another low-level input overhaul: split out low-level mouse input,

remove references to ncurses key values from the global shortcut list
and restructure it to specify function key values when needed, hook up
verbatim input to the edit window, and do a few miscellaneous cleanups

 CVS code -
+- General:
+	- Minor overhaul and abstraction of the lowest level of mouse
+	  input, mostly adapted from the code in do_mouse() that handles
+	  clicking on the shortcut list.  New function do_mouseinput();
+	  changes to do_mouse(). (DLR)  David Benbennick: Add a few
+	  efficiency tweaks.
+	- Modify the shortcut structure so that instead of having two
+	  miscellaneous key values (misc1 and misc2), there is one key
+	  value reserved for function keys (func_key) and one
+	  miscellaneous key value (misc), and tweak the
+	  shortcut-handling code to deal with this.  These changes allow
+	  NANO_OPEN(PREV|NEXT)_ALTKEY to work properly when added to the
+	  shortcut entries for NANO_OPEN(PREV|NEXT)_KEY.  Also remove
+	  the values in the shortcut list that were made redundant by
+	  the low-level input overhaul, use toupper() instead of
+	  subtracting 32 from values for greater code readability, and
+	  eliminate use of adding 32 to values when testing for toggles,
+	  as get_kbinput_accepted() converts toggle values to lowercase
+	  before returning them. (DLR)
+	- Hook up the verbatim input functions so that verbatim input
+	  can be used in the edit window.  New function
+	  do_verbatim_input(); changes to do_char(). (DLR)  Additional
+	  minor tweaks to do_char() by David Benbennick.
