* Add config option to hide issue events Adds a config option `HIDE_ISSUE_EVENTS` to hide most issue events (changed labels, milestones, projects...) on the issue detail page. If this is true, only the following events (comment types) are shown: * plain comments * closed/reopned/merged * reviews * Make configurable using a list * Add docs * Add missing newline * Fix merge issues * Allow changes per user settings * Fix lint * Rm old docs * Apply suggestions from code review * Use bitsets * Rm comment * fmt * Fix lint * Use variable/constant to provide key * fmt * fix lint * refactor * Add a prefix for user setting key * Add license comment * Add license comment * Update services/forms/user_form_hidden_comments.go Co-authored-by: Gusted <williamzijl7@hotmail.com> * check len == 0 Co-authored-by: wxiaoguang <wxiaoguang@gmail.com> Co-authored-by: zeripath <art27@cantab.net> Co-authored-by: Gusted <williamzijl7@hotmail.com> Co-authored-by: 6543 <6543@obermui.de>
