FC API: hoverText, alpha, showName support (patch)

Hello,

I'd like to introduce a patch for API attributes to support "hoverText, alpha, showName" parameters also.

This attribute is more likely to be applied in a general fashion, then:
hoverText: [0] => 'String value'

These attributes are more likely to be applied in a particular fashion, then:
alpha: [name] => '#'
showName [name] =>'#'

Thank you for your consideration.
