I read up on it some more this morning and British punctuation is basically a bit finicky. You can never add punctuation that isn't part of the actual quote (which is what American lets you do) but that doesn't mean you always include the original punctuation either.

If you have a quote at the end of a sentence you put the period outside the quotation marks to avoid having to write it like this: Only having the period inside the quotation marks in this case would only denote the end of a sentence within the quote, not the end of the larger sentence.
 * Unfortunately, "No one thought it was funny.".

You can have double punctuation if you're not repeating the same punctuation though, so Would be a valid way to write things.
 * She asked, "Where is the cat?".

And if the quote stands on its own (like the quotes at the top of pages) it can simply be since you don't need a period outside the quotation marks to denote the end of a larger sentence.
 * "No one thought it was funny."

I hope my explanation makes sense, I'm pretty sure I've got it right but if I've misunderstood something it would definitely be good to get it cleared up sooner rather than later.
