City pages started

Trying to make sure we can do Giverny, I ran across a great train->bike route for getting there. Looks like it beats the heck out of a bus, so I created a Paris page and slapped it in there, the first of our Cities pages. I'll create some sort of cities/day-by-day schedule later, but this is a start.

Also, the WikiStyle page is a good quick reference to make the wiki do most common tricks.
