bug: Compile fails when a schema avsc has a record name with underscores in it

[eljeko]

An Avro schema with underscores in the name of record brakes the compile, eg:

{
  "type" : "record",
  "namespace" : "",
  "name" : "my_name",
  "fields" : [...]
}

In the go generate phase produces a my_name.go with a struct named my_name but the template in generateRegistry.go will create a declaration like this:

var my_name MyName

Because is used function {{camel .}} that removes the underscores.

The current workaround is to remove underscores from names.
