Alert widget final - Githubissues

if an existing widget is being edited (as opposed to a widget being created) the /alert/check_alerts endpoint is called and the response compared to the widget's config data - updating it (but not saving it) as required,
ui form updated so only one alert "type" (min/max) can be set for the widget,

removed fade in/out effect as it was leaving the component contents blurry,
small styling tweaks,
updated table to reflect a single alert type (min/max) and to display alert "status",

uses it's own stored config data initially when loaded,
unless alert is "triggered" it checks for updated status from /alert/check_alerts on a loop until the alert is "triggered",
if response from /alert/check_alerts indicates that the alert has been triggered the widget's config is updated and saved and the new status is displayed,
small styling tweaks,
updated table to reflect a single alert type (min/max) and to display alert "status" ( as per AlertPreview),
updated dimensions to reflect new react-container-dimensions based layout
