Change the specificity to "a, b, c" three-segment representation

specificityArray: the result as an array of numbers e.g. [0, 1, 0, 0]

Selectors Level 3 only has a,b,c

Safari's developer tools also only show a,b,c.

@yisibl Polypane actually uses specificity! The first 0 is there to represent inline styles, which trump all. Since they are not applicable when dealing with CSS selectors directly, we hide them for clarity.
