ToolMessage (ANTLR Master build control POM 3.2 API)

```
public class ToolMessage
extends Message
```
A generic message from the tool such as "file not found" type errors; there is no reason to create a special object for each error unlike the grammar errors, which may be rather complex. Sometimes you need to pass in a filename or something to say it is "bad". Allow a generic object to be passed in and the string template can deal with just printing it or pulling a property out of it. TODO what to do with exceptions? Want stack trace for internal errors?
