Pass 'i' flag to regex if !caseSensitive

[mkpelletier]

This may be some low-hanging fruit that will greatly simplify regular expressions. Rather than specify caseSensitive in the Regexp options, use the configuration settings. This would allow users to make use of the i flag when writing their expressions.

Where do you think a call to https://github.com/otacke/h5p-essay/blob/master/scripts/essay.js#L899 is missing? Feel free to create a pull request.

Ah, thanks... I missed that. Is this live on h5p.com? It doesn't seem to work there. It is funny because I remember suggesting this patch several years ago.

Yes, this is live on H5P.com as far as I know, but you may want to ask the H5P core team for H5P.com support.
