Support multiple locales concurrent

This commit extends the plugin to support loading and using mutliple
locales at the same time. All strings are stored with their language
code. The plugins gets a new `lang` setting denoting the default locale.
For each HTML tag, the plugin will lookup `lang` attribute from the tag,
the configured default lang, or fallback to english.

It will use the `strings` object directly, if no lang key is found at
all, therefore it supports loading and running with older or custom
locale files that are directly assigning strings.
