Add gitignore for node projects.

Source: github/gitignore
Initial commit.

yo express
Remove some stuff I don't need.
Remove more crap and build scaffold.
Delete more crap.

In a stirring turn of events, I've gotten rid of more shit that
I don't need.

I also rewrote the routes file. I'm trying this thing where I
write the most hipster code that I can think of. Inspired by fat.
Change one tiny little thing.
Condense into one file and add a lovely header.
Make naming consistent.
More features and whimsy.
