Localization

[mdiller]

Slash commands are apparently eventually going to add support for localization, meaning I'll be able to easily provide localization for commands and their descriptions etc. If I end up doing this it would make sense to also update all of the static/return strings in mangobyte to have similar localized versions. Another factor is dotabase, which has access to the data it needs to be able to do localization of dota data, but would need to be entirely restructured to allow for it. Looks like a lot of work but maybe ill get around to it sometime.
