Store Orbi Configuration in XML Format

Saving the Orbi configuration to a file produces a binary file (gibberish).  This is convenient for the programmer.  One command will write a C structure to disk.  "Done."  One command will also read from file to structure.  The point of saving the configuration is in case "something goes wrong" and the user wants to revert the configuration back to a known state.  The most common practice is to save the configuration, reset the Orbi to factory settings, and read in the configuration.

Suppose, however, something has indeed gone wrong in the configuration.  Writing it out puts garbage on disk.  Doing a factory reset and reading the configuration back in again brings the garbage back into memory.  If the configuration file was written out in XML (plain text), the Orbi would have to parse each line as it was read back in and could catch errors.  In addition, a program could be written to validate the configuration file, line at a time, and detect parameters that do not have valid settings.
