Store newlines as <br /> tag in new posted Notes

[mnd]

ActivityStream assumes that content is HTML message: https://www.w3.org/TR/2017/REC-activitystreams-vocabulary-20170523/#dfn-content To fullfill this assumption save newlines as <br /> during post creation

• Target version: master

Summary

Suggested change should allow to store post in manner that allows to display it correctly on the web. Looks like other fediverse instances behave in similar manner. My only doubt is what better: use nl2br php function to have both newlines and <br \> tag, or use replace() call to have only <br \> tag

Replace is better because mastodon uses "white-space: pre-wrap" as default style and using <br \>\n will look ugly on mastodon web.
