Always use "--" in "dom parse" when document is interpolated
This is a safety measure to make sure that the document parsed is never confused with an option, when the document starts with a "-". In the best case, the error message provided by "dom parse" might be misleading. This might be a problem for user contributed documents (passed as variables, or return values from functions).
The double dash is supported in tdom since version 0.9.0.
Fixed regression test and make more use of "aa_test_start" and "aa_test_end"
This change reduces the errors in the log file a lets run the regression test (on my site) without reported errors as reported by acs_kernel__server_startup_ok.
