Changed BureauRegistry to use Launcher and updated bureau tests

* Moved the thane-specific TestClientMain out into src/thane and renamed 
  BureauTestClient
* Removed server name and port from the registry init and from the Launcher/
  CommandGenerator parameters. These can be inserted by the caller
* Converted all the asc junk to compc/mxmlc the same as msoy does it
* Moved the test client main function into src/as land
* Added extdeps.suffix alternative approach since tests/build.xml does not
  get launched from nifty ooo-libs container
* Fixed bureau test targets
* Moved avmthane to overridable property and corrected out of date default
* Converted BureauRegistry code to deal with Launcher objects and added shim
  to preserve use of CommandGenerator
* Fixed narya build to remove thane-config.xml after building aslib
