Added cmd option "--empty-class <match-empty|match-none|error>".

This option controls re2c actions when it encounters empty character
class (e.g. [], [^\0x00-\xFF] or [\0x00-\xFF]\[\0x00-\xFF]):
    match-empty (default) - match on empty input
    match-none - fail to match on any input
    error - compilation error

This is a final fix for bug #61 "empty character class [] matches empty string".
