Bug - changed scallop version.

org.fusesource.scalate use reflection in version 2.10.0 and scallop in version 0.9.4 use reflection in version 2.10.1. When I try to run codegen in IDE or use it as dependency (local maven) then compiler throw error 
```
Exception in thread "main" org.fusesource.scalate.TemplateException: scala.reflect.internal.TreeInfo.firstArgument(Lscala/reflect/internal/Trees$Tree;)Lscala/reflect/internal/Trees$Tree;
	at org.fusesource.scalate.TemplateEngine.compileAndLoad(TemplateEngine.scala:732)
	at org.fusesource.scalate.TemplateEngine.compile(TemplateEngine.scala:346)
	at com.wordnik.swagger.codegen.Codegen.compileTemplate(Codegen.scala:185)
	at com.wordnik.swagger.codegen.Codegen$$anonfun$3.apply(Codegen.scala:140)

``` 
I can not find newer stable version of org.fusesource.scalate so change scallop version to older is way to redeem the problem.
