Add types of all html properties

[oldrich-s]

I propose to add all the html properties from TypeScript lib into the HyperScript.

Specifically I propose to add:

type MutablePartial<T extends { [x: string]: any }, K extends string> = {
	[P in K]?: MutablePartial<T[P], keyof T[P]>;
}

interface Hyperscript {
	<K extends keyof ElementTagNameMap>(selector: K, attributes: Attributes & MutablePartial<ElementTagNameMap[K], keyof ElementTagNameMap[K]>, ...children: Children[]): Vnode<any, any>;

...

and to modify

(selector: string, attributes: Attributes, ...children: Children[]): Vnode<any, any>;

into

(selector: string, attributes: Attributes & MutablePartial<HTMLElement, keyof HTMLElement>, ...children: Children[]): Vnode<any, any>;

And then to remove

/** The class name(s) for this virtual element, as a space-separated list. */
className?: string;

from Attributes as it is already included in HTMLElement.

This way gives a complete intellisense of all html elements also including all style properties. Mutable extension must be there to convert readonly style into mutable one. Partial to make all props optional.

Ok, a little simplification. Hyperscript starts with:

interface Hyperscript {

	<K extends keyof ElementTagNameMap>(selector: K, attributes: Attributes | Partial<ElementTagNameMap[K]>, ...children: Children[]): Vnode<any, any>;

and Attributes interface is:

interface Attributes extends Lifecycle<any, any> {
	
	style?: Partial<CSSStyleDeclaration>;

	/** The class name(s) for this virtual element, as a space-separated list. */
	class?: string;
	/** A key to optionally associate with this element. */
	key?: string | number;
	/** Any other virtual element properties, including attributes and event handlers. */
	[property: string]: any;
}

So MutablePartial is not necessary. Seems to work just fine for me ;)

@czb thanks for taking the time to look into this, and it looks promising. Unfortunately I've been swamped at work lately and haven't had a lot of time to try this out.

If you get tired of waiting you're always free to create a PR for DefinitelyTyped and add the appropriate tests.
