Support for Spanish

[Chew]

The bot will soon support Spanish translations. Your client will translate in-client commands and responses will be in Spanish if your server's locale is set to it. By default, it will be in English for any other language.

Tasks:

• Translate slash commands
• Translate responses
• Support Spanish game feed (Support for Spanish feeds #21)

MLB already supports Spanish game feeds, we just need to implement grabbing it.
