Modify status bubble text color.

Modify status bubble text color.

Change from 50% alpha to 60% alpha as starting point (as per sgabriel's
recommendation).

Add a second step where we calculate a readable color. This doesn't
affect the classic theme but makes the text a little darker in some
cases (like GTK mode).
