[Feature] Ability to send the device language to Mailchimp

[rmtmckenzie]

Is your feature request related to a problem? Please describe.
I'm using the mobile device sdk to update my audience tags so that I can segment my audience. I'd also like to send up the language so that my email campaigns can be sent in the right languages.

Describe the solution you'd like
It'd be great if it were possible to send up the device language (or optionally the app-specific language) through the mobile SDK.

Describe alternatives you've considered
I could set up a server instance which would use the marketing API, but this means a fair amount of overhead for something that seems like it could easily be supported.

Nevermind, figured out how to use merge fields.
