* CLOUDFLAREAPI: Adds CF_WORKER_ROUTE. - CLOUDFLAREAPI: Initial support for CF_WORKER_ROUTE. - Put CF_WORKER_ROUTE behind a per-domain feature-flag. - Adds Integration Test. - Create Cloudflare workers for tests. - Updates documentation. * Workaround for updateWorkerRoute causing stack overflow. * Sets AccountID. * Updates to latest master (Thanks @tresni!). * Removes $CLOUDFLAREAPI_ACCOUNTNAME. * Add alltrue() filter and -cfworkers flag * Final workers changes * alltrue() should be implemented like other filters. * Update documentation.
