Include ID in error and warning messages

Example:

```
[Warning] Compiler: Could not find main syntax module with name
FOUNDRY-MAIN-SYNTAX in definition.  Use --syntax-module to specify one. Using
FOUNDRY-MAIN as default. [missing-syntax-module]
```

Then the user knows what ID to refer to to suppress the warning:

```
-Wno missing-syntax-module
```
