Overflowing int

[Matt Sherman]

Hi, excited to try goose but on my first goose up, am getting:

goose_main.go:26: constant 20130928175851 overflows int

...which appears to be a Go error (not the database, which I see is bigint). I look at the generated goose_main.go, and it looks like the version needs to be int64. Will send a pull request if desired.
