Title: Allow salt modules to be refreshed on demand.

As an example for the above feature:

```yaml
python-pip:
cmd:
- run
- cwd: /
- name: easy_install --script-dir=/usr/bin -U pip virtualenv
- reload_modules: true
```

See the last line?
If no exception occurs in this state, after it's execution, salt **will** reload it's modules.
