replace   : to replace misspelled word

Quick start:
    You should add script item "spell_correction" to a bar (i suggest using the input_bar).
    On an misspelled word, press TAB to cycle through suggestions. Press any key on suggestion
    to replace misspelled word with current displayed suggestion.
    Also check script options: /fset %(s)s

IMPORTANT:
    "%(p)s.check.suggestions" option has to be set to a value >= 0 (default: -1 (off)).
    "%(p)s.color.misspelled" option is used to highlight current suggestion in "%(p)s_suggestion" item
    Using "%(p)s.check.real_time" the nick-completion will not work. All misspelled words
    in input_line have to be replaced first.
