Add String#match

[kou]

Because mruby removes String#match at https://github.com/mruby/mruby/commit/fd37bc53deb2d52fe3134838eab002dfb9ac35ab .

Thanks! Does this fix https://github.com/mattn/mruby-onig-regexp/issues/95 ?

[kou]

Unfortunately, this is unrelated.

For #95, we need to implement String#[]= and Regexp.last_match= something like this:

Thank you. Could you update your pull-request to include above changes?

[kou]

Should we include a fix for #95 into this? I can create a new pull request for #95. I think that it's better that we use separated pull requests because they are unrelated.

[mattn]

If it does not consume your time, please do, thank you.

[kou]

OK. I'll create a new pull request. Could you merge this pull request as is?

[kou]

Done: #97

[mattn]

Thank you so much.
