Following the discussion on [#74](#74), here are changes to the submit buttons so that they match theme/project color.
Border colors are set to match the button background.
I've also included a "bugfix" where the `editor-toolbar-button-background` parameter in the dark theme.css and variables.scss were missing the # sign.
I wasn't sure whether to remove the `form button` values from theme.css and variables.scss and left them, as I'm not sure they're used anywhere now
