Gson should provide an ability to customize field name mapping

[GoogleCodeExporter]

Currently Gson just uses the actual name of the field as the Json property
name. This should be customizable. For example, it should be possible to
convert camel-case into hyphenated, or Camel-cased with upper-case first
letter.

so, myFavoriteField in Java gets mapped to my-favorite-field or
MyFavoriteField in Json. 

One approach to achieve this is by providing a name translation policy in
GsonBuilder.
