Default values for pot header fields

[pryds]

By default, pot files are created with the following default information:

# Translations template for PROJECT.
# Copyright (C) 2014 ORGANIZATION
# This file is distributed under the same license as the PROJECT project.
# FIRST AUTHOR <EMAIL@ADDRESS>, 2014.
#
#, fuzzy
msgid ""
msgstr ""
"Project-Id-Version: PROJECT VERSION\n"
"Report-Msgid-Bugs-To: EMAIL@ADDRESS\n"
"POT-Creation-Date: 2014-01-18 15:01+0100\n"
"PO-Revision-Date: YEAR-MO-DA HO:MI+ZONE\n"
"Last-Translator: FULL NAME <EMAIL@ADDRESS>\n"
"Language-Team: LANGUAGE <[email protected]>\n"
"MIME-Version: 1.0\n"
"Content-Type: text/plain; charset=utf-8\n"
"Content-Transfer-Encoding: 8bit\n"
"Generated-By: Babel 1.0dev\n"

It would be very nice to be able to specify values for PROJECT, ORGANIZATION, VERSION, EMAIL@ADDRESS (in Report-Msgid-Bugs), i.e. info that translators aren't supposed to enter or change.
