Environment variables in crontabs

If you need to set an env var that is used for a bunch of cron jobs, you can set it once at the top of your crontab, and cron will be smart enough to make it available to all jobs specified.

```
PATH=/my/extra/paths/bin:$PATH

# MIN HOUR DOM MONTH DOW CMD Do something in a strange path
0     12   *   *     *   run_this_command_that_lives_somewhere_strange -rf *
```
