Config fix for eslint react/jsx-no-duplicate-props

[rommguy]

First - thanks for this amazing tool, it's one of the best tools I've used

Bug report -
The eslint rules here have a config problem with react/jsx-no-duplicate-props - ignoreCase param should be false.
Some APIs like Material UI TextField allow different props with case differences only. In the Material UI example a TextField can get inputProps for the input dom node, and InputProps for the Input component.
So the config for this rule should have ignoreCase: false

I'll be happy to create a PR for this
Thanks
