Pull supported language translations from Transifex. Usage:
node sync_tx_translations.js tx-project tx-resource path
tx-project: project on Transifex (e.g., scratch-editor)
tx-resource: resource within the project (e.g., interface)
path: where to put the downloaded json files
NOTE: TX_TOKEN environment variable needs to be set with a Transifex API token. See
the Localization page on the GUI wiki for information about setting up Transifex.
