T-shirt punctuation

'It reads:  "foo bar quux"' is a sentence so should have a terminating
period.  Technically that ought to be placed inside the quotes, but
putting it after distinguishes slogans which have their own punctuation
from ones which don't.

A couple of entries contain multiple sentences.  Some used two-space
separation between those sentences, some only one; make all use two.

Add a few new T-shirt messages, including a couple with pop culture
references which are only 10 years old instead of 20 or more....
