colored metal signs optional and display size

That a small change but for someone who try to prevent having one craft guide page per item (and multiples variants) it make all the difference :)
This mod is great but it would be even greater if it was easier to configure
like an option use_big_font_size that would change CHARS_PERLINE from 30 to 12  and NUMBER_OF_LINES from 6 to 3
(I tried to do that but I failed)
