Release v10.3.0

• (@GermanBluefox) Added: the icon selector offers a library of 448 icons for rooms, buildings, furniture, lighting, climate, windows and shading, security, energy, water, household appliances, multimedia, garden, weather, people and more. Every icon has a name in all 11 languages, and the search looks through all categories. The icons are taken from Material Design Icons (Apache License 2.0), painted with currentColor and loaded only when the dialog is opened. The classic room and device icons stay available as their own categories
• (@GermanBluefox) Added: getClassicIconTemplates() returns the classic room and function templates with ID, name and icon, so the admin does not need its own copy of them any more. loadIconLibrary() and getIconLibrarySvg() give access to the icon library
• (@GermanBluefox) Changed: onlyRooms and onlyDevices of IconSelector and IconPicker only choose the category that is opened first - all other categories stay available
• (@GermanBluefox) Fixed: the classic room templates used the ID windscreen and had no cellar, while the admin creates the enums vestibule and cellar
