Agniva De Sarker 62731a8b64 Correctly store language and platform mappings together (#3588)
Previously they were stored separately in their own arrays.
This made them disconnected, and impossible to know if a page
belonged to which platform and language combination.

This PR adds an array of objects called `targets` which contains
platform/language pairs.
