luci-base: expose system translations to JavaScript

Browse source 
Add a new /admin/translations/ endpoint which exposes the loaded system
translations as JavaScript file.

Once referenced by <script>, the endpoint will create a `window.TR` object
containing the entire translation string table for use on the client side.
