Daniel Richard G 398e09fe9e Revised the Perl scripts
* Use "#!/usr/bin/env perl" instead of "#!/usr/bin/perl", as this is better
  practice (it allows e.g. /usr/local/bin/perl to work when executing via
  the shebang)

* Use "use strict" and "use warnings"

* Declare variables with "my" as required by "use strict"

* Take an optional "srcdir" argument so that the scripts can find the icon
  files in a location other than ./icons/ -- this will make building
  outside of the source tree possible in the future

* Add a "this is a generated file" banner to the output, so that it can be
  clearly recognized as a machine-generated file that should not be
  hand-edited

* Minor regex tweaks
