InputTextProps not type correctly

[prozacgod]

This seems to fix the issue.

interface InputTextProps extends React.HTMLProps<HTMLInputElement> {
    [key: string]: any;
    onInput?(event: React.FormEvent<HTMLInputElement>): void;
    onKeyPress?(event: React.KeyboardEvent<HTMLInputElement>): void;
    keyfilter?: any;
    validateOnly?: boolean;
}

#525, seems to fix this one as well.
