Add language_helper.py

This script is intended to make managing the language files a
little easier.

This script reads the English and supplied other language files and
compares the 2 and reorders and rewrites the other language to a new
XML file such that all the strings are placed in the same order as
the English file. It will place commented out string lines for items
that are not present in the new file and will not include any strings
in the new file that are no longer present in the English source.
There is also a version tag that may be compared if present between
the English and other language in case a translation string changes.
