Invalid DOM properties in react icon components #604

Console output shows warnings about invalid properties:

• 'Warning: Invalid DOM property stroke-linecap. Did you mean strokeLinecap?'
• 'Warning: Invalid DOM property stroke-linejoin. Did you mean strokeLinejoin?'
• 'Warning: Invalid DOM property stroke-width. Did you mean strokeWidth?'
• ...etc.

So that these warnings are not shown, I suppose in the script for generating react components we need to convert all attributes into camelCase
