Classnames starting with numbers aren't highlighted

Take this bit of code : 

```
class 30Rnd_556x45_Stanag {
    ...
};
```

The classname won't be colored, because it's starting with a number! I don't know if something can be done for this issue, but I'd love to see all my classes in the same color. It can be weird with files containing a large number of magazine classes.
