add new infoWidget component

this adds a new component, which is 2 labels
(left the title and right the text) with a
small progressbar

it has a method updateValue, where it takes a string and
a value from 0 to 1 and updates the right label
and the progressbar

the progressbar gets a different css class at >60% and
>90% (i added some css classes to make it yellow and red
respectively)

the warning and critical thresholds are customizable

this will be used in a new version of the statusview
