Jeedom compatibility -UTF8 compatibility - local - variable appdata

[belgotux]

• Add jeedom compatibility with condition based on provisioned variables
• Add a condition on $env:APPDATA : if you run it manually use it, but in service it never go in the user folder and use a variable in Settings.local.ps1 (take from chriscolden fork)
• Add UTF8 compatibility (powershell and UTF8 is crap....) and tested in french en english
• Add local languages settings example (en/fr) and base on .gitignore use a Settings.local.ps1
• Add information to the readme and bugfix a dependence for using c:\scripts and not the project directory to set nssm.exe as a service

Maybe need to check if the compatibility with HA is keeping
