split off specials from conky.c
As a side effect, font and colour specific stuff got outsourced, too. This is because the apropriate functions are used by conky.c as well as specials.c, so they should be kept on their own. In the long term I hope for positive impact on the X11 integration mess. (Take e.g. the mass of X11 ifdefs cluttering conky.c.) Though this commit contains no optimisations in this direction, just plain outsourcing, to ensure minimised (intended: none) changes to conky's interface behaviour.
