Dominik Riebeling 9f7c6a1745 genlang: add VOICE_ prefix to unused voice-only strings. 
voicefont uses the id prefix VOICE_ to recognize voice-only strings. Unused ids
get a NOT_USED prefixed entry to keep order correct. However, since this
applies to voice-only entries as well voicefont doesn't recognize those as
voice entries and puts them at the end of the lang strings table. This messes
up the order in the created voice file, so add VOICE_ as prefix so voicefont
can identify them.

# A note for future users and readers: The original v1 language system allowed
# the build to create and use a different language than english built-in. We
# removed that feature from our build-system, but the build scripts still had
# the ability. But, starting now, this ability is no longer provided since I
# figured it was boring and unnecessary to write support for now since we
# don't use it anymore.

Usage: genlang [options] <langv2 file>
-p=<prefix>
Make the tool create a [prefix].c and [prefix].h file.
-b=<outfile>
Make the tool create a binary language (.lng) file named [outfile].
The use of this option requires that you also use -e, -t and -i.
-u
Update language file. Given the translated file and the most recent english
file, you\'ll get an updated version sent to stdout. Suitable action to do
when you intend to update a translation.
-e=<english lang file>
Point out the english (original source) file, to use that as master
language template. Used in combination with -b, -u or -s.
-s
Sort the Update language file in the same order as the strings in the
English file.
-t=<target>
Specify which target you want the translations/phrases for. Required when
-b or -p is used.
The target can in fact be specified as numerous different strings,
separated with colons. This will make genlang to use all the specified
strings when searching for a matching phrase.
-i=<target id>
The target id number, needed for -b.
-o
Voice mode output. Outputs all id: and voice: lines for the given target!
-v
Enables verbose (debug) output.

# How update works:
#
# 1) scan the english file, keep the whole <phrase> for each phrase.
# 2) read the translated file, for each end of phrase, compare:
# A) all source strings, if there's any change there should be a comment about
# it output
# B) the desc fields
#
# 3) output the phrase with the comments from above
# 4) check which phrases that the translated version didn't have, and spit out
# the english version of those
