To Use:

1) Create a text file containing your new pediaicons.txt entries exactly as they should
   appear in pediaicons.txt
2) Run the program with the name of that file as its argument.
  ie) patcher test.txt


It will append any entries which were missing from pediaicons.txt to the bottom of
pediaicons.txt.   Those which were not missing are skipped.

It cannot handle civilopedia.txt yet as appending to the bottom of the file does not
seem appropriate in that text file.

The included test.txt is just an example to show how to setup a pediaicons.txt patch
file.

The source code is included in case someone wants to expand it to handle civilopedia
updates or fix any bugs I overlooked.
