* Email embed graphs * Allow attachment for non-html Add setting to webui Correct $auth setting * Cleanups, throw RrdGraphException instead of returning an error image. Generate the error image later, giving more control. Reduce code duplication a little * Style and lint fixes Change to flags * Add baseline for lint errors I don't know how to resolve * oopsie, changed the code after generating the baseline * Tiny cleanups. Make set DeviceCache primary, it is free. * Docs. * email_html note * Allow control of graph embed at the email transport level to override the global config. * Allow control of graph embed at the email transport level to override the global config. * Add INLINE_BASE64 to make it easier to create inline image tags
