Enabling rating worksheets in the rate routine plugin

The rate routine plugin has settings that enable the rate routine plugin to generate rating worksheets for a line of business. If rating worksheets are enabled for a line of business, the Show Rating Worksheet button appears on the Quote screen.

Enable rating worksheets in the plugin by making the following changes:

Set the WorksheetsEnabled parameter to true in the IRateRoutinePlugin registry.
In the LOBRateRoutineConfig.gs class, modify the worksheetsEnabledForLine override method to return true.
For example, you can turn on rating worksheets for a line of business by modifying the line-of-business configuration classes with an override to the worksheetsEnabledForLine method. For example, the following code in the CPRateRoutineConfig class enables rating worksheets for commercial property:
```
override function worksheetsEnabledForLine(linePatternCode : String) : boolean {
    return true
}
```
In the RateRoutinePlugin class, the worksheetsEnabledForLine method calls the line-specific implementation of worksheetsEnabledForLine.
