Simple config i18n

[cAttte]

the changes in #382 were applied to all four languages, which leads me to a minor suggestion: config file localization. it obviously doesn't have to be part of the actual program, just a part of the build system. this would let something like this

# config/en/imports/file-manage.nss
item(title='Hidden' checked=io.attribute.hidden(atrr)

# config/ko/imports/file-manage.nss
item(title='숨김' checked=io.attribute.hidden(atrr)

be simplified into something like this:

# config/imports/file-manage.nss
item(title='{{fileManage.attributes.hidden}}' checked=io.attribute.hidden(atrr)

// config/imports/strings.en.json
"fileManage.attributes.hidden": "Hidden"

// config/imports/strings.en.json
"fileManage.attributes.hidden": "숨김"

such simple functionality can be achieved with a simple script that looks something like (pseudo-code):

for (file in files)
    for (lang in langs)
        fs.write(lang.code + '/' + file.name,
            file.content.replace(/\{\{(.+?)\}\}/, (_, id) => lang.strings[id])

at first glance this might seem more complicated, but it would enable translators to focus on translating only, which is especially going to come in handy whenever new languages get added!
