Hurricane Servers .list files

Hurricane Server supports several .list files which can be used to tweak Hurricane Servers behavior. These files can be placed in the global config directory:

bouncesignatures.list
optimizations.list
- [Response Regex] | [retry interval]
deliverystatuscodes.list
The deliverystatuscodes.list file is used for two purposes.
- To control how Hurricane Server reports failures (as temporary or permanent) by the FailureType parameter of the OnFail() plugin event, and
- To cause a server response to generate an alert. The file has three columns delimited by the "~*~" character combination. The first column is the
```
[Response Regex]~*~[Temporary, Permanent, Default]~*~[Alert]
```
