Address WebLog size issue that limited number of entries

Added logic to sequentially transmit chunks of the HTML response String whenever it grows beyond 1024 bytes.  This ensures the number of WebLog entries does not create a very large HTML String that eats up all the free heap space.  WebLog entries are now only limited by storage of the entries themselves.  Tested successfully with 500 entries.
