Considering that we introduced credentials in 8.0.0, in the next version we should:

• add/modify SP: TigAddUser that only add user (wouldn't take password, possibly with additional parameter to set account status, by default it would be value denoting new_account)
• remove TigAddUserPlainPw
• completely remove "DB Properties" (TigPutDBProperty and TigGetDBProperty)
• possibly remove TigUserLogin, TigUserLoginPlainPw and TigUserLogout and only leave stubs in documentation as reference (especially avoid updating tig_users table during log-in and log-out to avoid delays in plugins, if this information is required point to auditlog!)
• remove TigOnlineUsers , TigOfflineUsers and TigInitdb
