X11BARS.WAX v0.99.04 update

Updated code to:

1. Recognize Canadian area codes (to permit Canadian users to add all US and Canadian NPAs but exclude all other NPAs).
2. Added protection against NPA.TXT corruption: Validate NPA value from NPA.TXT before sending value to SL1 interface.  (Value must be between 200 and 999).
3. Updated NPA.TXT to include all area codes created since last update.  Still excluding 800, 866, 877 and 900 NPAs to permit these to be manually configured as SPNs.
4. Updated X11BARS documentation.

Thank you Andrew Chapelle for the bug report.
