Updated the signature for the overridable parseResourceFile method so that it now can receive an optional second argument that contains information about the resource file, such as the language and path. This information can be used by the parser code to conditionalize parsing. In particular, this facility can be used to provide different parsing behavior for the primary language resource files, where some projects need to default the string value to the string key / id - this occurs with projects where the string ID is the primary language source text, and where the string value is left empty in the primary language resource files.
