This patch provides the ability to override most aspects of the configuration output provided to Oxidized. This is now backwards compatible with any current groups defined previously but allows for extra features such as group overrides in Oxidized as well as IP changes (for hosts that are treated differently inside Oxidized), as well as ProxyHost additions. Of course, this goes further and allows for any flag that can be defined within Oxidized to be mapped in the config.
Examples
1) Define a group for these hosts
```php
$config['oxidized']['maps']['group']['sysname'][] = array('regex' => '/^(foo|bar)/', 'group' => 'myGroup');
$config['oxidized']['maps']['group']['sysname'][] = array('regex' => '/^(baz)/', 'group' => 'anotherGroup');
```
2) Provide a proxy host for these hosts to bounce through
```php
$config['oxidized']['maps']['ssh_proxy']['sysname'][] = array('regex' => '/foo/', 'ssh_proxy' => 'mySshProxyHost');
$config['oxidized']['maps']['ssh_proxy']['sysname'][] = array('regex' => '/bar/', 'ssh_proxy' => 'anotherSshProxyHost');
```
3) Allow overrides of IP addresses so the external DNS is not used for connections
```php
$config['oxidized']['maps']['ip']['sysname'][] = array('regex' => '/baz/', 'ip' => '10.10.0.23');
$config['oxidized']['maps']['ip']['sysname'][] = array('regex' => '/lala/', 'ip' => '192.168.0.243');
```
As already mentioned, this doesn't stop with the above examples.
