To allow a localization service method to be reliably executed for multiple projects, the common config options object should be cloned, so that options that are merged in per project do not cross-contaminate execution.
Implemented a simple about method for the localization service that displays the config options for the project.
Added a bug fix to treat empty, self-closing source and target tags as specifying empty string values.
A bit more doc for the localization automation guide.
