Title: Dependencies version printing.

This commit allows printing the deps version numbers from salt's cli tools(as long as the option parser used is `salt.utils.parser`). It can be useful in some debugging report situations.

Example output:

```
$ salt --versions-report
Salt: 0.10.1
Python: 2.7.3 (default, Apr 20 2012, 22:44:07)
Jinja2: 2.6
M2Crypto: 0.21.1
msgpack-python: 0.1.13
pycrypto: 2.4.1
PyYAML: 3.10
PyZMQ: 2.1.11
```
