Update CSS flex box property values

* auto as new (default) value for min-height and min-width
* content as valid value of flex-basis
* correct browser support for display: flex and display: inline-flex
* remove IE support for old unprefixed flexbox display values
(incorrect info)
* add -webkit-flex and -webkit-inline-flex values for display.
