Expose all stored field signatures of an Objekt

[alessandropellegrini]

This patch allows to get all stored field signatures of an object. The use case here is when someone want, e.g., to inspect an Enum and retrieve all possible constants.

Your use case is unclear. Why isn't enough to get the Enum's Klass object, and then reading its fields with getStoredFieldSignatures()?
