Add resource for adding locales

[blacksails]

It would be nice to have an LWRP for installing additional locales without setting them.

This would be useful when using phps setlocale, to format dates etc.

can't the package resource be used to install the correct locale package?

i see, it installs the locale on debian/ubuntu using locale-gen, which it doesn't do on the other platforms. i'm not certain if that should even be supported if it can't be supported cross-platform. it definitely needs to be extracted out to its own API that can be separated from the API to set the locale.
