new_day script

Start a new day by running . ./new_day N where N is the number of the challenge.

That script automates a bunch of stuff, because my time is limited:

1. Sets up a new rust binary project in the dayN directory
2. Downloads the input for the first part of the challenge into the root of that project
3. Copies over the main.rs from the template file
4. cds into the project and opens up the main.rs in vim.

Note that day1 and day2 don't contain both solutions because they weren't tracked in git at the time.
