Simplify keep-alive action. Now the interval is based on session_lifetime,
which means it's executed only if needed for session keeping (reset interval on every action).

Temporarily remove check-recent request, it will be replaced by new global system refresh request in future.
Use keep_alive setting as auto-refresh request interval (allow no-refresh mode)
Clarify keep-alive setting, move it to User Interface section, change label
to "Refresh (check for new messages, etc.)", allow no-refresh mode.
