This adds a new function "_edit_line" with enhanced cursor control for line editing in config.
I took the routine from new-config, and adjusted it to fit this config.
keys supported:
ctrl-a : beginning of line
ctrl-e : end of line
ctrl-k : kill to end of line
delete : deletes previous char
ctrl-del : deletes char under cursor
ESC : cancel editing
ctrl left/right : move cursor left/right
Escape now restores the previous string that was there.
Unfortunately, non of the signatures of functions that do editing ever react to the return value, and are all void, so ESC as cancel doesn't stop the config from being saved, or entering wifi passwords from stopping the process, but this is a limitation of the current functions, not the editing.
