Title: Enabled/disabled colour for positive/neutral/negative button

Changed colour of disabled button text to be a faded version of its enabled colour instead of the dark grey that can currently be seen. This behaviour can be seen in original Lollipop system dialogues, e.g., in the Add Network dialogue of the Settings app (faded/disabled SAVE button)
