ServerProperties (Power TAC intra-hour market-based balancing 1.7.0 API)

```
public interface ServerProperties
```
Supports server configuration by allowing components to retrieve property values from a standard Java properties file. The property values are searched from three locations; values in later locations override values in earlier locations.
1. server.properties in the top level of the server jarfile. This contains standard settings for all the standard server components.
2. A file named server.properties in the current directory.
3. A file provided on the command-line as the value of the config option.
