* Add win_hosts module
added win_hosts module for easier manipulation of hosts entries in "%windir%\system32\drivers\etc\hosts" for windows systems
* Update win_hosts.py
* Add alias support to win_hosts module (#1)
* win_hosts supports aliases
added support for adding / removing aliases from a host entry, rather than adding a new entry
added ability for win_hosts to detect aliases:
`192.168.1.1 alias1 alias2 alias3`
```
win_hosts:
host_name: alias2
ip_address: 192.168.1.1
```
will result in `192.168.1.1 alias1 alias3`
also includes `replace` and `add` as options for `ip_action` (`replace` is default)
for example:
```
192.168.1.1 my_reused_alias
192.168.1.2 my_reused_alias
```
with
```
win_hosts:
host_name: my_reused_alias
ip_address: 192.168.1.3
ip_action: add
```
the result will be
```
192.168.1.1 my_reused_alias
192.168.1.2 my_reused_alias
```
but with `ip_action=replace` the result would be
```
192.168.1.3 my_reused_alias
```
