Using encoding SourceGuardian API from unprotected script

SourceGuardian API functions are part of the SourceGuardian loader and so are only available when the SourceGuardian loader is loaded into PHP. This may be done automatically by the run-time loader of the SourceGuardian protected script, or when the SourceGuardian loader is installed server-wide in php.ini and loaded when PHP starts.

sg_load_file() SourceGuardian API function will return the file's data as-is without decryption when:

- it runs from unprotected script with loader installed server-wide (this is useful for debugging purposes, see below)

- it loads the template or data file which was not encoded by SourceGuardian

sg_encode_file() SourceGuardian API function will write the file's data as-is without encryption:

- when run from an unprotected script with the loader installed server-wide
