Colortbl for table colors

[MRoth1910]

It appears that the package colortbl is missing from the commonheaders file or the calendrier file. (Unless I missed it in the first file.) I did some testing with the second, and the current calendrier file doesn't compile; arrayrulecolor is given as an undefined control sequence. Adding the above package fixes things, and it compiles wonderfully.

I use my own preamble file (in part since I don't have the same fonts to load) which is why it's possible that I missed the package call, but I don't think that I did.

I lean towards not including a calendar in any of the books. It is extremely annoying to make, and I fail to see what purpose it serves, I guess for establishing the ordo it's marginally faster to look at it rather than into the book? (but one would not have to look into the book, the sanctoral ribbon is already at today's date)
