[aquaria] [PATCH v2] Multi-Language support

[Henrik Holst]

Here is the second version of my multi-language patch to Aquaria.

This patch set enables multi language support in Aquaria, which language to use
is determined from the system default unless the user has configured
it in the config
file with the "Locale" element under the "System" element, for example
this to hard code
the language to be "en":

"<System>
    <Locale name="en" />
"

The patch works by adding a new function UserSettings::localisePath()
that takes a path to a file
and returns a new language specific name if one is found, if no
language specific version of the
file is found then the orginal filename is returned. So this means
that everything is completely
transparant.

If told to open "scripts/vox/naija_intro-music.txt" this function will
look for and stop at the first file it finds
out of (if we assume a language of "sv_SE":

1. locales/sv_SE/scripts/vox/naija_intro-music.txt
2. locales/sv/scripts/vox/naija_intro-music.txt
3. scripts/vox/naija_intro-music.txt

That way it's possible to support regional variants of languages while at
the same time bailing back to the original (english) file if no language
specific file is found. This is also implemented when reading text files
from mods so mods can contain translations as well.

In this version of the patch set, the following text-files have
multi-language support:

data/ingredients.txt
data/help_header_mac.txt
data/help_header.txt
data/help_bindsong.txt
data/help_energyform.txt
data/help_start.txt
data/help_end_mac.txt
data/help_end.txt
data/achievements.txt
data/stringbank.txt
scripts/vox/*.txt

And for mods the following text files:

ingredients.txt
stringbank.txt
audio/*.txt

What is left to do for proper multi-language support is to also load some
of the graphics and sounds this way so people can translate them as well. And
 of course the problem with the bitmap font only supporting 7-bit
english letters
must be solved one day, or we simply will load a locale specific font file...
