Release Notes:

Details:
  - Added grammar to recognize formal parameter initializers,
    param = expression.

  - initializers are checked to see that they are null (a current
    restriction) if not, a warning is issued.

  - For all runtimes but SWF9, the initializers are removed.
    Eventually that behavior could change for all runtimes
    (no removal of initializers) and with more work, we could
    fully support them.

  - changed the unparser to support printing the initializers
    (not as pretty as it should be).

  - removed some unused code in CodeGenerator, JavascriptGenerator.

Tests:
  - smokecheck SWF8/DHMTL
  - added test/optargs.lzx to test all cases, this is
    now accepted by SWF8/DHTML.  Gives reasonable results
    in DHTML.  I believe more work may be needed in SWF8
    to support this.
  - temporarily copied the functions from optargs.lzx to
    LzNode to demonstrate it working for SWF9.
