Disable Polling, Translation, and More

• Polling is disabled. The integration no longer fetches the website data every 2 seconds (yah!). New alerts are received via the push channels (mobile and tzevaadom). Website data is still fetched, but only after a new alert is received.
• Tzevaadom channel is now used also for pre-alert updates.
• Entity names are getting localized. See below the Hebrew version.
• The manual icon selection option was removed. The default icons are used.
