Title: Change `env-file` parameter type from string to array

As @michaelsauter suggested (https://github.com/michaelsauter/crane/issues/94#issuecomment-54230522) I made the `env-file` parameter to be handled the same way `env` param is.

Usage example:
```yaml
---
containers:
testing:
image: ubuntu
run:
cmd: bash
env-file:
- tests/1.env
- tests/2.env
interactive: true
rm: true
tty: true
```
