Self reload Assist sentences on sentences updates !

This version adds Assist auto reload on updated Assist sentences.
The Recalbox script .sh had many improvements and optimizations

• On first install or updates, if custom sentences have been updated,
  tries to reload Home Assistant Assist sentences without asking for a new restart.
  Only if fails to reload, it will ask the user to restart.
• Reorder settings buttons, because save/load were not in the same order that in the card
• Change JSON sent from Recalbox to Home Assistant, from imageUrl to imagePath.
  Home Assistant will recompose the full URL on his own, because he knowns the host+port of this Recalbox.
  Integration is still compatible with older versions, it reads imageUrl is existing in JSON, else it composes itself the URL with imagePath.
• Duplicate Recalbox script in two versions (only one required) :
  • Recalbox/userscripts/home_assistant_notifier.sh:
    • Improve to get Home Assistant IP adress only if the event is useful
    • Optimization : as soon as the Home Assistant IP is solved, it is saved in cache to make next executions quicker
    • Add shutdown and reboot events in Recalbox script, to say to Home Assistant that the Recalbox is turning off (was only listing stop until that)
  • Recalbox/userscripts/home_assistant_notifier(permanent).sh EXPERIMENTAL :
    • New version, that is permanent : the script is launched only once, and loops on events.
    • It should be way more optimized, and waits to be connected to network to send MQTT messages.
    • Create a timestamped logs file : /recalbox/share/system/logs/home_assistant_integration/*
• Both scripts now send their version to Home Assistant, in the JSON message,
  "scriptVersion": "home_assistant_notifier.sh:v1.3.1" or "scriptVersion": "home_assistant_notifier(permanent).sh:v1.3.1"
• Auto clean scripts logs
• Persist scriptVersion as Recalbox extra state attribute
• Added host attribute, so the REcalbox card uses the configured host to access webmanager, instead of ip_adress that doesn't exist yet
• Added recalboxIpAddress attribute, instead of setting as the host
• When Home Assistant (re)starts, pings the Recalbox to directly set as ON (without game info) or OFF, instead of waiting for the first ON MQQT message
• Change Recalbox Card chip color in light theme.
