Prevent StringIO from showing up in salt -d
mimic the vm_info command to make it able to get state for all VMs
Added layman module for layman tool.

Layman is a third-party package repository (overlay) management
tool for Gentoo.
Added import for salt.utils to layman module
Added import of salt.utils to gentoolkit.

Virtual was always returning false do to missed import
Added module for eix tool (for Gentoo)
Merge pull request #3063 from shadowfax-chc/develop

Added layman module for layman tool (for Gentoo).
Added functions for sync and update to eix module
If eix is available, run eix-sync for pkg.refresh_db for Gentoo

If eix is installed call eix-sync since eix-sync calls
emerge --sync but can also sync overlays (via layman). If eix is not
installed, fallback on emerge --sync

Added module for eix tool (for Gentoo)
`W0142` added to `.pylintrc` disabled checkers.

`W0142` is triggered when `*` or `**` magic is used, for example:

```python
my_func(*args, **kwargs)
```

This PyLint checker is now disabled since we use it quite a lot, and, in fact, take advantage of this magic.
Replaced OS environ checks with `salt.utils.is_windows()`.
Formatting of eclean_dist function in gentoolkit module
