Content Model Author

Browse Source 
Make sure that the Author in the content model is only ever updated int he following circumstacnes:
- The member updates their displayname or avatar
- A previously hidden author line is shown

This is done by only doing a full reset on initialisation or when a previously hidden author is shown. The rest of the time we only reset the other content in the message, i.e. everything below the author line.
