* Initial page design for DNS Not Found and 404 errors with Places-based suggestions, Search, and Try Again.
* Entity definitions for the initial page design have been added to "netError.dtd".
* Now have a C++ implementation of the Levenshtein edit distance algorithm(finding nearest string matches), which is accessible in Places Sqlite queries.
* 404 errors are intercepted and redirected to the new error page, but only the Places-based suggestions feature is functional.
* DNS Not Found errors use the new page design, but it’s not functional at all yet.
